Supported Formats

Sources: Wikipedia and IANA
This page details all the supported Datasaur formats, provides examples for each format and clarifies expected file structure where appropriate.

Note: Through file transformers we can customize the output format.
TXT
TXT file is a simple file format that contains unformatted text and can be easily opened and edited using a basic text editor. It is commonly used for storing and exchanging data, code, and other textual information.

TSV
A TSV (tab-separated values) file is a simple text format for storing data in a tabular structure. A TSV file encodes a number of records that may contain multiple fields.
Each record is represented as a single line.
Each field
value is represented as text.
Fields in a record are separated from
one other by the tab character .
Note that because is a special character for this format, fields that contain tabs are not allowed in this encoding.
The header (first) line of this encoding contains the name of
each field, separated by tabs.
Example
Book Title    Author    Genre
Sherlock Holmes: A Study in Scarlet    Sir Arthur Conan Doyle    Fiction
To Kill a Mockingbird    Harper Lee    Fiction
Alan Turing: The Enigma    Andrew Hodges    Non fiction
Humble Pie    Gordon Ramsay    Non fiction
The Little Prince    Antoine de Saint-Exupéry    Fiction
IOB (specialized .tsv)
IOB (inside, outside, beginning) is a common labeling format for labeling tokens in computational linguistics (ex: named-entity recognition). IOB is also a .tsv, but conforms to the following rules:
The B- prefix before a tag indicates that the tag is the beginning of a chunk.
The I- prefix before a tag indicates that the tag is inside a chunk.
The B- tag is used only when a tag is followed by a tag of the same type without O tokens between them.
The O tag indicates that a token does not belong to a chunk.
Example
Sherlock    B-PER
Holmes    I-PER

CSV
A CSV (comma-separated values) file is a delimited text file that uses a comma to separate values. Each line of the file is a data record. Each record consists of one or more fields, separated by commas. The use of the comma as a field separator is the source of the name for this file format.
A CSV file typically stores tabular data (numbers and text) in plain text, in which case each line will have the same number of fields.
Example
Book Title,Author,Genre
Sherlock Holmes: A Study in Scarlet,Sir Arthur Conan Doyle,Fiction
To Kill a Mockingbird,Harper Lee,Fiction
Alan Turing: The Enigma,Andrew Hodges,Non fiction
Humble Pie,Gordon Ramsay,Non fiction
The Little Prince,Antoine de Saint-Exupéry,Fiction
💡 As for now, a row-based project using CSV format does not support answers containing ;. We treat it as multiple answers. For example, the answer is She brings some flowers: rose; sunflower; and daisy. It will be interpreted as three answers that containShe brings some flowers: rose ,sunflower , and daisy.
XLS and XLSX
​XLS and XLSX is a well-known format for Microsoft Excel documents that was introduced by Microsoft XLS is an older format that was used in older versions of Excel, while XLSX is a newer format that is the default in more recent versions of Excel. Both formats allow users to input, organize, and analyze data in rows and columns. They also support features such as formulas, charts, and graphs. XLSX is a more efficient format that offers better data recovery and larger file size limits.
Example

JSON
​JSON (JavaScript Object Notation), or JSON Simplified, is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and array data types (or any other serializable value).
A JSON file may contain the following data structures:
An object is an unordered set of name/value pairs.
An object begins with {left brace and ends with }right brace. Each name is followed by :colon and the name/value pairs are separated by ,comma.
An array is an ordered collection of values.
An array begins with [left bracket and ends with ]right bracket. Values are separated by ,comma.
A value can be a string in double quotes, or a number, or true or false or null, or an object or an array. These structures can be nested.
A string is a sequence of zero or more Unicode characters, wrapped in double quotes, using backslash escapes. A character is represented as a single character string. A string is very much like a C or Java string.
A number is like a C or Java number, except that the octal and hexadecimal formats are not used.
Whitespace can be inserted between any pair of tokens. Excepting a few encoding details, that completely describes the language.
In the example below, here are the objects recognized at Datasaur.
text: the sentence.
entities: array of label applied
text: the token
type: the label applied.
start_idx: the character position in the labeled token.
The character position uses zero-based index.
end_idx: the last character position + 1 (because end_index does not include the last character).
The character position uses zero-based index.
JSON (Simplified) export format limitation:
Can't export arrow label
Can't export label multi sentence
Example
[
  {
    "text": "The new series Narcos created by Chris Brancato , Eric Newman and Carlo Bernard , represents a pretty ambitious step for Netflix .",
    "entities": [
      {
        "text": "Narcos",
        "type": "TITLE",
        "start_idx": 15,
        "end_idx": 21
      },
      {
        "text": "Chris Brancato",
        "type": "PER",
        "start_idx": 33,
        "end_idx": 47
      },
      {
        "text": "Carlo Bernard",
        "type": "PER",
        "start_idx": 66,
        "end_idx": 79
      },
      {
        "text": "Eric Newman",
        "type": "PER",
        "start_idx": 50,
        "end_idx": 61
      },
      {
        "text": "Netflix",
        "type": "ORG",
        "start_idx": 121,
        "end_idx": 128
      }
    ]
  }
]
JSON_TABULAR
JSON_TABULAR is a derivative of the JSON format that is used to represent table data format (in the form of an array of objects). You can choose this format if you are working on row-based labeling.
Example
[
  {
    "Book Title": "Sherlock Holmes: A Study in Scarlet",
    "Author": "Sir Arthur Conan Doyle",
    "Genre": "Fiction"
  },
  {
    "Book Title": "To Kill a Mockingbird",
    "Author": "Harper Lee",
    "Genre": "Fiction"
  },
  {
    "Book Title": "Alan Turing: The Enigma",
    "Author": "Andrew Hodges",
    "Genre": "Non fiction"
  },
  {
    "Book Title": "Humble Pie",
    "Author": "Gordon Ramsay",
    "Genre": "Non fiction"
  },
  {
    "Book Title": "The Little Prince",
    "Author": "Antoine de Saint-Exupéry",
    "Genre": "Fiction"
  }
]
TSV_NON_IOB
TSV_NON_IOB is a derivative of the TSV format that represents data that does not follow the IOB format - for example, B-GEO is just GEO. If your project is token-based (with or without arrows), you can choose this format for export.
A TSV_NON_IOB file contains the following data structure (this explanation is based on our example below):
1.#FORMAT: the file header.
2.#Text: the sentence representation.
3.1-1: the sentence-token.
1.The first 1 indicates the sentence number.
2.The second 1 indicates the token number.
4.0-3: the character index.
5.TITLE[1]: the label applied.
1.[1] indicates uniquely identify annotation across lines.
6.Column 5: indicates layer 2.
7.author[2-1]: the label on the arrow.
1.2 indicates the arrow’s token origin.
2.1 indicates the arrow’s token destination.
8.Column 7: indicates layer 4.
9.Column 8: indicates layer 5.
Note: column 5, 7, and 8 will be filled if you label the token in the mentioned layers.
_\_💡_We built this format to be compatible with [_WebAnno](https://webanno.github.io/webanno/releases/3.4.5/docs/user-guide.html#sect_webannotsv)_._​

CoNLL-U
Universal Dependencies use a revised version of the CoNLL-X format called CoNLL-U. Sentences consist of one or more word lines, and word lines contain the following fields:
1.sent_id: Sentence id.
2.text: Sentence.
3.ID: Word index, integer starting at 1 for each new sentence; may be a range for multiword tokens; may be a decimal number for empty nodes (decimal numbers can be lower than 1 but must be greater than 0).
4.FORM: Word form or punctuation symbol.
5.LEMMA: Lemma or stem of word form.
6.UPOS: Universal part-of-speech tag.
7.XPOS: Language-specific part-of-speech tag; underscore if not available.
8.FEATS: List of morphological features from the universal feature inventory or from a defined language-specific extension; underscore if not available.
9.HEAD: Head of the current word, which is either a value of ID or zero (0).
10.DEPREL: Universal dependency relation to the HEAD (root iff HEAD = 0) or a defined language-specific subtype of one.
11.DEPS: Enhanced dependency graph in the form of a list of head-deprel pairs.
12.MISC: Any other annotation.

CoNLL_2003
​CoNLL_2003 is usually used for POS tagging and named entity recognition labeling. All data files contain one word per line with empty lines representing sentence boundaries. At the end of each line there is a tag which states whether the current word is inside a named entity or not. The tag also encodes the type of named entity. Each line contains four fields:
1.The word
2.Part of-speech tag
3.Chunk tag
4.Named entity tag
Note: Importing or exporting files with conll_2003 format can be done if you checked the following task settings.
Tokens and token spans should have at most one label.
Allow arrows to be drawn between labels. Checking this setting will activate layer feature.
You could do POS tagging on Layer 0 and NER tagging on Layer 1. If you export the file with conll_2003, the result will be as shown as example below.
Example
Sherlock NNP B-Person O
Holmes NNP I-Person O
become VB O O
widely RB O O
popular JJ O O
in IN O O
1891 CD B-Year O

JSON_ADVANCED
JSON_ADVANCED is a proprietary Datasaur format designed in collaboration with our users to capture all possible data. This format is commonly used for partial token labeling projects. You can also use it when exporting token-based with arrow projects, such as coreference and dependency.
A JSON_ADVANCED file may contain the following data structures:
1.Sentences field
1.id: the sentence position.
2.content: the text of the sentence.
3.tokens: the tokens form of the sentence.
4.labels
1.l: the label applied.
2.layer: the layer position of the labels. This field is reserved for a project where a labeling of multiple tag set at once. For now you can disregard this field and this field is always set to 0.
3.id: the unique identifier of a label.
1.If the id has 9 segments, this indicates span label. For example, INNM0ViFwo8LluMTaTIK9:0:0:14:0:0:18:6:0 and here's the explanation <label set item id>:<layer>:<sidS>:<s>:<charS>:<sidE>:<e>:<charE>:<index>.
2.If the id has 21 segments, this indicates arrow label. For example, tfc1FkbbEk9fOLx6haR1s:0:INNM0ViFwo8LluMTaTIK9:0:0:14:0:0:18:6:0:Oq_VuB0s_N7D8ZY0rgYsg:0:0:0:0:0:2:5:0:0 and here's the explanation <label set item id>:<arrow layer>:<….. origin id>:<….destination id>:<arrow index>.
4.hashCode: Datasaur's code to represent label information __
1.Span label. For example, SPAN:gpe:0:0:0:4:0:0:0:4:3:0:undefined:undefined. Below is the explanation:
1.type:label set item id:layer or label set index:start cell line:cell index:start token index: start char index: end cell line: end cell index: end token index: end char index: counter.
2.Arrow label. For example, ARROW:dyC-o1HBnn49dcqDSphmJ:1:0:0:0:0:0:0:10:6:0:SPAN:geo:0:0:0:0:0:0:0:0:4:0:undefined:undefined:SPAN:geo:0:0:0:10:0:0:0:10:6:0:undefined:undefined. Below is the explanation:
1.type:label set item id:layer or label set index:start cell line:cell index:start token index: start char index: end cell line: end cell index: end token index: end char index: counter:<span label: origin>:<span label: destination>.
5.documentId: the id of document.
6.sidS, sidE: the sentence starting and ending position of a label in 0-based index. In Datasaur, it is possible that a label spans across sentences.
