53-447: Luminate Data, LLC (formerly MRC Data and P-MRC Data ) is a provider of music and entertainment data . Established as a joint-venture in 2020, it brought together Nielsen Music, Alpha Data (formerly BuzzAngle Music) and Variety Business Intelligence (formerly TVtracker). In December 2019, Eldridge Industries ' Valence Media , then parent company of Billboard , acquired Nielsen's music data business, reuniting it with Billboard for

106-488: A mass noun in singular form. This usage is common in everyday language and in technical and scientific fields such as software development and computer science . One example of this usage is the term " big data ". When used more specifically to refer to the processing and analysis of sets of data, the term retains its plural form. This usage is common in the natural sciences, life sciences, social sciences, software development and computer science, and grew in popularity in

159-472: A Hot 100 is decided in 2013. Sales data from cash registers is collected from 14,000 retail, mass merchant, and non-traditional (on-line stores, venues, digital music services, etc.) outlets in the United States, Canada, UK and Japan. The requirements for reporting sales to Nielsen Music are that the store has Internet access and a point of sale (POS) inventory system. Submission of sales data must be in

212-436: A basis for calculation, reasoning, or discussion. Data can range from abstract ideas to concrete measurements, including, but not limited to, statistics . Thematically connected data presented in some relevant context can be viewed as information . Contextually connected pieces of information can then be described as data insights or intelligence . The stock of insights and intelligence that accumulate over time resulting from

265-584: A climber's guidebook containing practical information on the best way to reach Mount Everest's peak may be considered "knowledge". "Information" bears a diversity of meanings that range from everyday usage to technical use. This view, however, has also been argued to reverse how data emerges from information, and information from knowledge. Generally speaking, the concept of information is closely related to notions of constraint, communication, control, data, form, instruction, knowledge, meaning, mental stimulus, pattern , perception, and representation. Beynon-Davies uses

318-404: A common view, data is collected and analyzed; data only becomes information suitable for making decisions once it has been analyzed in some fashion. One can say that the extent to which a set of data is informative to someone depends on the extent to which it is unexpected by that person. The amount of information contained in a data stream may be characterized by its Shannon entropy . Knowledge

371-659: A description of other data. A similar yet earlier term for metadata is "ancillary data." The prototypical example of metadata is the library catalog, which is a description of the contents of books. Whenever data needs to be registered, data exists in the form of a data document . Kinds of data documents include: Some of these data documents (data repositories, data studies, data sets, and software) are indexed in Data Citation Indexes , while data papers are indexed in traditional bibliographic databases, e.g., Science Citation Index . Gathering data can be accomplished through

424-553: A few decades. Scientific publishers and libraries have been struggling with this problem for a few decades, and there is still no satisfactory solution for the long-term storage of data over centuries or even for eternity. Data accessibility . Another problem is that much scientific data is never published or deposited in data repositories such as databases . In a recent survey, data was requested from 516 studies that were published between 2 and 22 years earlier, but less than one out of five of these studies were able or willing to provide

477-414: A limited repertoire of characters, often very small, many are only usable to represent text in a limited subset of human languages. Unicode is an attempt to create a common standard for representing all known languages, and most known character sets are subsets of the very large Unicode character set. Although there are multiple character encodings available for Unicode, the most common is UTF-8 , which has

530-510: A long-term basis through the RIAA certification system; it has never used either Nielsen SoundScan or the store-calling method. The first Billboard Hot 100 number-one song via Nielsen SoundScan was " Set Adrift on Memory Bliss " by P.M. Dawn . Other changes would also largely impact the Hot 100 in the future, consisting of radio-only songs being able to chart in 1998, and YouTube views playing part of how

583-470: A primary source (the researcher is the first person to obtain the data) or a secondary source (the researcher obtains the data that has already been collected by other sources, such as data disseminated in a scientific journal). Data analysis methodologies vary and include data triangulation and data percolation. The latter offers an articulate method of collecting, classifying, and analyzing data using five possible angles of analysis (at least three) to maximize

636-428: A terminating newline character, normally LF. Additionally, POSIX defines a printable file as a text file whose characters are printable or space or backspace according to regional rules. This excludes most control characters, which are not printable. Prior to the advent of macOS , the classic Mac OS system regarded the content of a file (the data fork) to be a text file when its resource fork indicated that

689-408: A text editor, human-readable content is presented to the user. This often consists of the file's plain text visible to the user. Depending on the application, control codes may be rendered either as literal instructions acted upon by the editor, or as visible escape characters that can be edited as plain text. Though there may be plain text in a text file, control characters within the file (especially

742-530: A two-character combination: carriage return (CR) and line feed (LF). It is common for the last line of text not to be terminated with a CR-LF marker, and many text editors (including Notepad ) do not automatically insert one on the last line. On Microsoft Windows operating systems, a file is regarded as a text file if the suffix of the name of the file (the " filename extension ") is .txt . However, many other suffixes are used for text files with specific purposes. For example, source code for computer programs

795-426: Is flat file ) is a kind of computer file that is structured as a sequence of lines of electronic text . A text file exists stored as data within a computer file system . In operating systems such as CP/M , where the operating system does not keep track of the file size in bytes, the end of a text file is denoted by placing one or more special characters, known as an end-of-file (EOF) marker, as padding after

848-467: Is strictly necessary. A simple text file may need no additional metadata (other than knowledge of its character set ) to assist the reader in interpretation. A text file may contain no data at all, which is a case of zero-byte file . The ASCII character set is the most common compatible subset of character sets for English-language text files, and is generally assumed to be the default file format in many situations. It covers American English, but for

901-405: Is the awareness of its environment that some entity possesses, whereas data merely communicates that knowledge. For example, the entry in a database specifying the height of Mount Everest is a datum that communicates a precisely-measured value. This measurement may be included in a book along with other data on Mount Everest to describe the mountain in a manner useful for those who wish to decide on

954-443: Is the longevity of data. Scientific research generates huge amounts of data, especially in genomics and astronomy , but also in the medical sciences , e.g. in medical imaging . In the past, scientific data has been published in papers and books, stored in libraries, but more recently practically all data is stored on hard drives or optical discs . However, in contrast to paper, these storage devices may become unreadable after

1007-404: Is the plural of datum , "(thing) given," and the neuter past participle of dare , "to give". The first English use of the word "data" is from the 1640s. The word "data" was first used to mean "transmissible and storable computer information" in 1946. The expression "data processing" was first used in 1954. When "data" is used more generally as a synonym for "information", it is treated as

1060-564: Is the source of sales information for the Billboard music charts . The company operates the analytics platform Music Connect, Music 360 and Broadcast Data Systems (which tracks airplay of music), the latter of which was shut down in September 2022. Nielsen SoundScan began tracking sales data for Nielsen on March 1, 1991. The May 25 issue of Billboard published Billboard 200 and Country Album charts based on SoundScan "piece count data", and

1113-734: Is usually kept in text files that have file name suffixes indicating the programming language in which the source is written. Most Microsoft Windows text files use ANSI, OEM, Unicode or UTF-8 encoding. What Microsoft Windows terminology calls "ANSI encodings" are usually single-byte ISO/IEC 8859 encodings (i.e. ANSI in the Microsoft Notepad menus is really "System Code Page", non-Unicode, legacy encoding), except for in locales such as Chinese, Japanese and Korean that require double-byte character sets. ANSI encodings were traditionally used as default system locales within Microsoft Windows, before

1166-495: The Billboard charts than before, and their chart success helped increase the genre's popularity. In addition, SoundScan sales data quickly found use in the promotion departments at major record labels, to persuade radio station music directors to play tracks by high-selling alternative artists such as Nirvana . Alpha Data (formerly, but commonly known as BuzzAngle Music ) was a music analytics firm which provided statistics for

1219-443: The 20th and 21st centuries. Some style guides do not recognize the different meanings of the term and simply recommend the form that best suits the target audience of the guide. For example, APA style as of the 7th edition requires "data" to be treated as a plural form. Data, information , knowledge , and wisdom are closely related concepts, but each has its role concerning the other, and each term has its meaning. According to

1272-489: The British pound sign , the euro sign , or characters used outside English, a richer character set must be used. In many systems, this is chosen based on the default locale setting on the computer it is read on. Prior to UTF-8, this was traditionally single-byte encodings (such as ISO-8859-1 through ISO-8859-16 ) for European languages and wide character encodings for Asian languages. Because encodings necessarily have only

1325-433: The act of observation as constitutive, is offered as an alternative to data for visual representations in the humanities. The term data-driven is a neologism applied to an activity which is primarily compelled by data over all other factors. Data-driven applications include data-driven programming and data-driven journalism . Text file A text file (sometimes spelled textfile ; an old alternative name

1378-435: The advantage of being backwards-compatible with ASCII; that is, every ASCII text file is also a UTF-8 text file with identical meaning. UTF-8 also has the advantage that it is easily auto-detectable . Thus, a common operating mode of UTF-8 capable software, when opening files of unknown encoding, is to try UTF-8 first and fall back to a locale dependent legacy encoding when it definitely is not UTF-8. On most operating systems,

1431-433: The best method to climb it. Awareness of the characteristics represented by this data is knowledge. Data are often assumed to be the least abstract concept, information the next least, and knowledge the most abstract. In this view, data becomes information by interpretation; e.g., the height of Mount Everest is generally considered "data", a book on Mount Everest geological characteristics may be considered "information", and

1484-434: The binary alphabet. Some special forms of data are distinguished. A computer program is a collection of data, that can be interpreted as instructions. Most computer languages make a distinction between programs and the other data on which programs operate, but in some languages, notably Lisp and similar languages, programs are essentially indistinguishable from other data. It is also useful to distinguish metadata , that is,

1537-429: The calling system) often did not match (for instance Paula Abdul 's " Promise of a New Day " and Roxette 's " Fading Like a Flower " reached much higher Hot 100 peaks than their actual sales and airplay would have allowed them to). Although most record company executives conceded that the new method was far more accurate than the old, the chart's volatility and its geographical balance initially caused deep concern, before

1590-639: The change and the market shifts it brought about were accepted across the industry. Tower Records , the country's second-largest retail chain, was originally not included in the sample because its stores were equipped with different technology to measure sales. At first, some industry executives complained that the new system—which relied on high-tech sales measurement rather than store employee estimates—was based on an inadequate sample, one that favored established and mainstream acts over newcomers. The Recording Industry Association of America also tracks sales (or more specifically, shipments minus potential returns) on

1643-477: The collected data using a statistical calculation called " weighting ". This assigns a multiplier to each category of stores, to compensate for the number of similar stores not covered by the sampling program. Sales in each category are multiplied accordingly. Such a system is vulnerable to exploitation if it is known which stores are included in the sampling program. To inflate their reported chart sales, some indie labels were reported to purposefully target stores in

1696-617: The concept of a sign to differentiate between data and information; data is a series of symbols, while information occurs when the symbols are used to refer to something. Before the development of computing devices and machines, people had to manually collect data and impose patterns on it. With the development of computing devices and machines, these devices can also collect data. In the 2010s, computers were widely used in many fields to collect data and sort or process it, in disciplines ranging from marketing , analysis of social service usage by citizens to scientific research. These patterns in

1749-444: The course of a controlled scientific experiment. Data are analyzed using techniques such as calculation , reasoning , discussion, presentation , visualization , or other forms of post-analysis. Prior to analysis, raw data (or unprocessed data) is typically cleaned: Outliers are removed, and obvious instrument or data entry errors are corrected. Data can be seen as the smallest units of factual information that can be used as

1802-408: The data are seen as information that can be used to enhance knowledge. These patterns may be interpreted as " truth " (though "truth" can be a subjective concept) and may be authorized as aesthetic and ethical criteria in some disciplines or cultures. Events that leave behind perceivable physical or virtual remains can be traced back through data. Marks are no longer considered data once the link between

1855-600: The end of each line. Other operating systems, such as OpenVMS and OS/360 and its successors , have record-oriented filesystems , in which text files are stored as a sequence either of fixed-length records or of variable-length records with a record-length value in the record header. "Text file" refers to a type of container, while plain text refers to a type of content. At a generic level of description, there are two kinds of computer files: text files and binary files . Because of their simplicity, text files are commonly used for storage of information. They avoid some of

1908-502: The endianness of the file content. Although UTF-8 does not suffer from endianness problems, many Microsoft Windows programs (i.e. Notepad) prepend the contents of UTF-8-encoded files with BOM, to differentiate UTF-8 encoding from other 8-bit encodings. On Unix-like operating systems, text files format is precisely described: POSIX defines a text file as a file that contains characters organized into zero or more lines, where lines are sequences of zero or more non-newline characters plus

1961-571: The ethos of data as "given". Peter Checkland introduced the term capta (from the Latin capere , "to take") to distinguish between an immense number of possible data and a sub-set of them, to which attention is oriented. Johanna Drucker has argued that since the humanities affirm knowledge production as "situated, partial, and constitutive," using data may introduce assumptions that are counterproductive, for example that phenomena are discrete or are observer-independent. The term capta , which emphasizes

2014-409: The first Hot 100 chart to debut with the system was released on November 30, 1991. Previously, Billboard tracked sales by calling stores across the U.S. and asking about sales—a method that was inherently error-prone and open to outright fraud. Indeed, while transitioning from the calling to tracking methods, the airplay and sales charts (already monitored by Nielsen) and the Hot 100 (then still using

2067-979: The first time since its spin-off to E5 Global Media from Nielsen Business Media. It was renamed MRC Data in 2020 after Eldridge Industries merged Valence with the film and television studio MRC . and was then brought under its PMRC joint venture with Penske Media Corporation as P-MRC Data . It was renamed once more to Luminate Data in March 2022. In August 2022, the MRC merger was unwound, with Eldridge Industries taking sole ownership of its stake in PMRC. Nielsen Music, originally established by Mike Fine and Mike Shalett in 1991, collects music consumption and sales weekly and makes this available every Sunday (for album sales) and every Monday (for song sales) to subscribers, which include record companies, publishing firms, music retailers, independent promoters, film and TV companies, and artist managers. It

2120-540: The form of a text file consisting of all the UPCs sold and the quantities per UPC on a weekly basis. Sales collected from Monday–Sunday or Sunday–Saturday are reported every Monday and made available to subscribers every Wednesday. Anyone selling a music product with its own UPC or ISRC may register that product to be tracked by Luminate. Not all retailers participate in the SoundScan program, so total CD sales are projected from

2173-444: The last line in a text file. In modern operating systems such as DOS , Microsoft Windows and Unix-like systems, text files do not contain any special EOF character, because file systems on those operating systems keep track of the file size in bytes. Some operating systems, such as Multics , Unix-like systems, CP/M, DOS, the classic Mac OS , and Windows, store text files as a sequence of bytes, with an end-of-line delimiter at

2226-538: The mark and observation is broken. Mechanical computing devices are classified according to how they represent data. An analog computer represents a datum as a voltage, distance, position, or other physical quantity. A digital computer represents a piece of data as a sequence of symbols drawn from a fixed alphabet . The most common digital computers use a binary alphabet, that is, an alphabet of two characters typically denoted "0" and "1". More familiar representations, such as numbers or letters, are then constructed from

2279-792: The music industry, including record sales and music streaming. TVtracker, founded in 1999 by Mark Hoebich, tracks and analyzes all aspects of U.S. filmed entertainment, including television, feature film and digital entertainment, with coverage of everything from pilot pickups and series orders to motion picture development and post-production. The company evolved into Variety Business Intelligence and operates as Luminate Film & TV. Data Data are collected using techniques such as measurement , observation , query , or analysis , and are typically represented as numbers or characters that may be further processed . Field data are data that are collected in an uncontrolled, in-situ environment. Experimental data are data that are generated in

2332-495: The name text file refers to a file format that allows only plain text content with very little formatting (e.g., no bold or italic types). Such files can be viewed and edited on text terminals or in simple text editors . Text files usually have the MIME type text/plain , usually with additional information indicating an encoding. DOS and Microsoft Windows use a common text file format, with each line of text separated by

2385-522: The petabyte scale. Using traditional data analysis methods and computing, working with such large (and growing) datasets is difficult, even impossible. (Theoretically speaking, infinite data would yield infinite information, which would render extracting insights or intelligence impossible.) In response, the relatively new field of data science uses machine learning (and other artificial intelligence (AI)) methods that allow for efficient applications of analytic methods to big data. The Latin word data

2438-405: The problem of reproducibility is the attempt to require FAIR data , that is, data that is Findable, Accessible, Interoperable, and Reusable. Data that fulfills these requirements can be used in subsequent research and thus advances science and technology. Although data is also increasingly used in other fields, it has been suggested that the highly interpretive nature of them might be at odds with

2491-406: The problems encountered with other file formats, such as endianness , padding bytes, or differences in the number of bytes in a machine word . Further, when data corruption occurs in a text file, it is often easier to recover and continue processing the remaining contents. A disadvantage of text files is that they usually have a low entropy , meaning that the information occupies more storage than

2544-547: The program for on-site sales promotions. Also, other labels were found shipping boxes of their CDs to be scanned by complicit retailers in the program. The incorporation of SoundScan tracking by the Billboard charting system was cited by the industry as a possible cause of the early '90s popularization of alternative music in the United States. An explanation floated was that the previous call system under-represented marginal genres. Under SoundScan, more accurate data on alternative music sales allowed these acts to appear higher in

2597-448: The requested data. Overall, the likelihood of retrieving data dropped by 17% each year after publication. Similarly, a survey of 100 datasets in Dryad found that more than half lacked the details to reproduce the research results from these studies. This shows the dire situation of access to scientific data that is not published or does not have enough details to be reproduced. A solution to

2650-457: The research's objectivity and permit an understanding of the phenomena under investigation as complete as possible: qualitative and quantitative methods, literature reviews (including scholarly articles), interviews with experts, and computer simulation. The data is thereafter "percolated" using a series of pre-determined steps so as to extract the most relevant information. An important field in computer science , technology , and library science

2703-474: The synthesis of data into information, can then be described as knowledge . Data has been described as "the new oil of the digital economy ". Data, as a general concept , refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing . Advances in computing technologies have led to the advent of big data , which usually refers to very large quantities of data, usually at

2756-560: The transition to Unicode. By contrast, OEM encodings, also known as DOS code pages , were defined by IBM for use in the original IBM PC text mode display system. They typically include graphical and line-drawing characters common in DOS applications. "Unicode"-encoded Microsoft Windows text files contain text in UTF-16 Unicode Transformation Format. Such files normally begin with byte order mark (BOM), which communicates

2809-523: The type of the file was "TEXT". Lines of classic Mac OS text files are terminated with CR characters. Being a Unix-like system, macOS uses Unix format for text files. Uniform Type Identifier (UTI) used for text files in macOS is "public.plain-text"; additional, more specific UTIs are: "public.utf8-plain-text" for utf-8-encoded text, "public.utf16-external-plain-text" and "public.utf16-plain-text" for utf-16-encoded text and "com.apple.traditional-mac-plain-text" for classic Mac OS text files.
