17 Simple Analytic Mechanisms
目次
This chapter describes a module for associating simple analyses and interpretations with text elements. We use the term analysis here to refer to any kind of semantic or syntactic interpretation which an encoder wishes to attach to all or part of a text. Examples discussed in this chapter include familiar linguistic categorizations (such as ‘clause’, ‘morpheme’, ‘part-of-speech’ etc.) and characterizations of narrative structure (such as ‘theme’, ‘reconciliation’ etc.). The mechanisms presented in this chapter are simpler but less powerful than those described in chapter 18 Feature Structures.
Section 17.1 Linguistic Segment Categories introduces elements which can be used to characterize text segments according to the familiar linguistic categories of sentence or s-unit, clause, phrase, word, morpheme, character, and punctuation mark. These elements represent special cases of the generic seg element described in section 16.3 Blocks, Segments, and Anchors.
Section 17.2 Global Attributes for Simple Analyses introduces an additional global attribute which allows passages of text to be associated with specialized elements representing their interpretation. These ‘interpretative’ elements (span and interp) are described in detail in section 17.3 Spans and Interpretations. They allow the encoder to specify an analysis as a series of names and associated values,71 each such pair being linked to one or more stretches of text, either directly, in the case of spans, or indirectly, in the case of interpretations.
Finally section 17.4 Linguistic Annotation revisits the topic of linguistic analysis, and illustrates how these interpretative mechanisms may be used to associate simple linguistic analysis with text segments.
TEI: Linguistic Segment Categories¶17.1 Linguistic Segment Categories
In this section we introduce specialized linguistic segment category elements which may be used to represent the segmentation of a text into the traditional linguistic categories of sentence, clause, phrase, word, morpheme, characters, and punctuation marks.
TEI: Words and Above¶17.1.1 Words and Above
Although different languages have very different rules about what constitutes a ‘word’ or a ‘sentence’, these remain generally useful concepts. In this section we discuss elements provided for marking up linguistic units down to the word level, however defined.
- s (s-unit) 文に相当するテキスト単位を示す.
- cl (clause) 言語学上の節を示す.
- phr (phrase) 文法上の句を示す.
- w (word) 文法上の語を示す(正書形である必要はない).
lemma 当該語の,辞書の見出し形を示す. lemmaRef provides a pointer to a definition of the lemma for the word, for example in an online lexicon.
As members of the att.segLike class, these elements all share the following attribute:
- att.segLike 任意の部分に使用される要素向けの属性を示す.
function 当該部分の役割を示す.
They also share attributes from att.typed:
- att.typed 要素を分類するための属性を示す.
type 当該要素の分類を示す. subtype 必要であれば,当該要素の下位分類を示す.
These elements are also all members of the model.segLike class, which is a subclass of model.phrase. They may thus appear anywhere that text is permitted within a document, when the module defined by this chapter is included in a schema.

Clauses may be further divided into phr elements in the same way. A text may be segmented directly into clauses, or into phrases, with no need to include segmentation at a higher level as well.

The type attribute on linguistic segment categories can be used to provide additional interpretative information about the category. The function attribute on the cl and phr elements can be used to provide additional information about the function of the category. Legal values for these two attributes are not defined by these Guidelines, but should be documented in the segmentation element of the encodingDesc element within the document's header. A general approach to the encoding of linguistic categories for parts of a text is discussed in section 17.4 Linguistic Annotation below.

This style of markup may introduce spurious new lines and blanks into the text. If the original layout is important, it should be explicitly encoded, using such facilities as the lb element, the global rend or rendition attributes, etc.
The w, m, and c elements are identical in meaning to the seg element with a type attribute of ‘w’, ‘m’, or ‘c’ respectively, and may occur wherever seg is permitted to occur. However, their content is more constrained than seg: for example, the w element should only contain w, m, c elements or pc elements, or plain text; the m element should contain only c or pc elements or plain text; both the c and pc elements should contain only plain text, most often only a single character or a sequence of graphemes to be treated as a single character. Consequently, while these more specific elements can be translated directly into typed seg elements, the reverse is not necessarily the case.

TEI: Below the Word Level¶17.1.2 Below the Word Level
It is sometimes helpful to markup explicitly sub-word components such as morphemes, characters, or punctuation.
- m (morpheme) 言語学上の形態素を示す.
- c (character) 文字を示す.
- pc (punctuation character) contains a character or string of characters regarded as constituting a single punctuation mark.
<m type="base">
<m type="prefix" baseForm="con">com</m>
<m type="root">fort</m>
</m>
<m type="suffix">able</m>
</w>
<seg type="base">
<seg type="prefix">com</seg>
<seg type="morph">fort</seg>
</seg>
<seg type="suffix">able</seg>
</seg>
There is a substantial linguistic difference between characters like letters or diacritics and punctuation marks. The former are used to construct meaningful units like morphemes or words. The latter are functionally independent units acting at the level of syntactic units. A word may consist of a single letter (for example ‘I’ in English), but this does not mean that we should use c instead of w to mark it up.
<c>M</c>
<c>O</c>
<c>A</c>
<c>I</c>
<w>doth</w>
<w>sway</w>
<w>my</w>
<w>life</w>
</phr>
<c>n</c>
<c type="punct">'</c>
<c>t</c>
</m>
<pc>
<g ref="#pelev">;</g>
</pc> natus est in bethlehem
<pc>.</pc>o <pc>.</pc> mira gratia...
<!-- elsewhere -->
<char xml:id="pelev">
<!-- definition of the punctus elevatus character -->
</char>
The pc element carries special attributes to record analyses of the functional behaviour or classification of the punctuation mark it contains. The unit attribute may be used, as on the milestone element to name the kind of unit which the punctuation mark delimits, for example a paragraph or section. The pre attribute may be used to indicate whether the punctuation precedes or follows the unit it delimits. The force attribute indicates the strength of the association between the punctuation mark and its adjacent word.
<pc unit="para" force="strong" pre="true">¶</pc>Incipit...
</p>
<w>
<m baseForm="do">did</m>
<m>n't</m>
</w>
<w lemma="do">do</w>
<w>it</w>
<pc>.</pc>
This segmentation, crude as it is, succeeds in representing the idea that did occurring as a morphological component of the word didn't has something in common with the word <do>. A further advantage of segmenting the text down to this level is that it becomes relatively simple to associate each such segment with a more detailed formal analysis, for example by providing a baseform, or morphological analysis at whichever level is appropriate. This matter is taken up in detail in section 17.4 Linguistic Annotation.
TEI: Global Attributes for Simple Analyses¶17.2 Global Attributes for Simple Analyses
When the module described by this chapter is selected, an additional attribute is defined for all elements:
- att.global.analytic 任意のテキスト部分への分析・解釈に関連するグローバル属性を示す.
ana (analysis) 属性anaを伴う要素の解釈を含む要素を示す.
The ana attribute may be specified for any element. Its effect is to associate the element with one or more others representing an analysis or interpretation of it. Its target should be one of the elements described in the section 17.3 Spans and Interpretations below, or some other interpretative element such as note, on which see section 3.8 Notes, Annotation, and Indexing or fs, on which see chapter 18 Feature Structures.
TEI: Spans and Interpretations¶17.3 Spans and Interpretations
The simplest mechanisms for attaching analytic notes in some structured vocabulary to particular passages of text are provided by the span and interp elements, and their associated grouping elements spanGrp and interpGrp.
- span テキスト部分に解釈的注釈を関連づける.
- spanGrp (span group) 要素spanをまとめる.
- interp あるテキスト部分とリンクする,特定の解釈的注釈をまとめる.
- interpGrp 責任者や分類を共にする,関連し合う解釈をまとめる.
These elements are all members of the class att.interpLike, and thus share the following attributes:
- att.interpLike 形式的分析や解釈を示す要素に付与される属性を示す.
type 当該部分で,どのような面が指摘されているのかを示す. 例としての値は以下の通り: 1] image; 2] character; 3] theme; 4] allusion inst (instances) 当該要素で示されている分析や解釈の実体を示す.
They also inherit the following attributes from att.global.responsibility:
- att.global.responsibility provides attributes indicating the agency responsible for some aspect of the text, the markup or something asserted by the markup, and the degree of certainty associated with it.
cert (certainty) 当該解釈や調整の確信度を示す. resp (responsible party) 当該解釈や調整の責任者を示す.例えば,編集者,翻訳者など.
The type attribute of the span and interp elements may be used to indicate that the annotations are of specific types, for example thematic or structural. The annotation itself is supplied as the content of the span or interp element. In the case of the span element, the span of text being annotated is indicated by values of the from, to or target attributes, used in combination as follows. If only the from attribute is supplied, then the span is coterminous with the element indicated by its value; if both from and to are supplied, the span runs from the start of the element indicated by the from attribute up to the end of the element indicated by the to attribute; if the target attribute is used, the span is defined by aggregating the contents of the (possibly non-contiguous) elements pointed to by its values. It is an error to supply only the to attribute; to supply more than one pointer value for either to or from attributes; or to supply either of these in conjunction with the target attribute. In the case of interp (see below), the span is indicated by a pointer from a link element or some similar mechanism. The resp attribute indicates the annotator responsible for this annotation.

Spans may also be used to represent structural divisions within a narrative, particularly when these do not coincide with the structure implied by the element structure. Consider the following narrative:
Sigmund, the son of Volsung, was a king in Frankish country. Sinfiotli was the eldest of his sons, the second was Helgi, the third Hamund. Borghild, Sigmund's wife, had a brother named — But Sinfiotli, her stepson, and — both wooed the same woman and Sinfiotli killed him over it.73 And when he came home, Borghild asked him to go away, but Sigmund offered her weregild, and she was obliged to accept it. At the funeral feast Borghild was serving beer. She took poison, a big drinking horn full, and brought it to Sinfiotli. When Sinfiotli looked into the horn, he saw that poison was in it, and said to Sigmund ‘This drink is cloudy, old man.’ Sigmund took the horn and drank it off. It is said that Sigmund was hardy and that poison did him no harm, inside or out. And all his sons could tolerate poison on their skin. Borghild brought another horn to Sinfiotli, and asked him to drink, and everything happened as before. And a third time she brought him a horn, and reproachful words as well, if he didn't drink from it. He spoke again to Sigmund as before. He said ‘Filter it through your mustache, son!’ Sinfiotli drank it off and at once fell dead.
Sigmund carried him a long way in his arms and came to a long, narrow fjord, and there was a small boat there and a man in it. He offered to ferry Sigmund over the fjord. But when Sigmund carried the body out to the boat, it was fully laden. The man said Sigmund should go around the fjord inland. The man pushed the boat out and then suddenly vanished.
King Sigmund lived a long time in Denmark in the kingdom of Borghild, after he married her. Then he went south to Frankish lands, to the kingdom he had there. Then he married Hiordis, the daughter of King Eylimi. Their son was Sigurd. King Sigmund fell in a battle with the sons of Hunding. And then Hiordis married Alf, the son of King Hialprec. Sigurd grew up there as a boy.
Sigmund and all his sons were tall and outstanding in their strength, their growth, their intelligence, and their accomplishments. But Sigurd was the most outstanding of all, and everyone who knows about the old days says he was the most outstanding of men and the noblest of all the warrior kings.

Note the use of an empty anchor element to provide a target for the ‘reconciliation’ unit which is normally part of the narrative pattern but which is not realized in the text shown.
The same analysis may be expressed with the interp element instead of the span element; this element provide attributes for recording an interpretive category and its value, as well as the identity of the interpreter, but does not itself indicate which passage of text is being interpreted; the same interpretive structures can thus be associated with many passages of the text. The association between text passages and interp elements must be made either by pointing from the text to the interp element with the ana attribute defined in section 17.2 Global Attributes for Simple Analyses, or by pointing at both text and interpretation from a link element, as described in chapter 16 Linking, Segmentation, and Alignment.

One obvious advantage of using interp rather than span elements for the Sigmund text is that the interp elements can be reused for marking up other texts in the same document, whereas the span elements cannot. On the other hand, the use of interp elements may require the creation of special text elements not otherwise needed (e.g. the seg and the join in the revised encoding of the text), whereas the use of span elements does not.
TEI: Linguistic Annotation¶17.4 Linguistic Annotation
By linguistic annotation we mean here any annotation determined by an analysis of linguistic features of the text, excluding as borderline cases both the formal structural properties of the text (e.g. its division into chapters or paragraphs) and descriptive information about its context (the circumstances of its production, its genre or medium). The structural properties of any TEI-conformant text should be represented using the structural elements discussed elsewhere in this chapter and in chapters 3 Elements Available in All TEI Documents, 4 Default Text Structure, and the various chapters of Part III. The contextual properties of a TEI text are fully documented in the TEI header, which is discussed in chapter 2 The TEI Header, and in section 15.2 Contextual Information.
Other forms of linguistic annotation may be applied at a number of levels in a text. A code (such as a word-class or part-of-speech code) may be associated with each word or token, or with groups of such tokens, which may be continuous, discontinuous, or nested. A code may also be associated with relationships (such as cohesion) perceived as existing between distinct parts of a text. The codes themselves may stand for discrete and non-decomposable categories, or they may represent highly articulated bundles of textual features. Their function may be to place the annotated part of the text somewhere within a narrowly linguistic or discoursal domain of analysis, or within a more general semantic field, or any combination drawn from these and other domains.
The manner by which such annotations are generated and attached to the text may be entirely automatic, entirely manual or a mixture. The ease and accuracy with which analysis may be automated may vary with the level at which the annotation is attached. The method employed should be documented in the interpretation element within the encoding description of the TEI header, as described in section 2.3.3 The Editorial Practices Declaration. Where different parts of a language corpus have used different annotation methods, the decls attribute may be used to indicate the fact, as further discussed in section 15.3 Associating Contextual Information with a Text.
As one example of such types of analysis, consider the following sentence, taken from the Lancaster/IBM Treebank Project (Leech and Garside (1991)).
Our discussion focuses on the way that this sentence might be analysed using the CLAWS system developed at the University of Lancaster but exactly the same principles may be applied to a wide variety of other systems.74 Output from the system consists of a segmented and tokenized version of the text, in which word class codes have been associated with each token. CLAWS offers outputs in a variety of non-XML and XML formats: for example, the simplest format for the sample sentence would be:
The_AT0 victim_NN1 's_POS friends_NN2 told_VVD police_NN2 that_CJT Kruger_NP0 drove_VVD into_PRP the_AT0 quarry_NN1 and_CJC never_AV0 surfaced_VVD
<w ana="#AT0">The </w>
<w ana="#NN1">victim</w>
<w ana="#POS">'s</w>

<w ana="#VVD">told </w>
<w ana="#NN2">police </w>
<w ana="#CJT">that </w>
<w ana="#NP0">Kruger </w>

This approach requires the text to be fully segmented, using the linguistic segment elements described in section 17.1 Linguistic Segment Categories, so that the scope of the ana attribute used to point to each interpretation is clearly defined. A further analysis into phrase and clause elements can be superimposed on the word and morpheme tagging in the preceding illustration. For example, CLAWS provides the following constituent analysis of the sample sentence (the word class codes have been deleted):
[N [G The victim's G] friends N] [V told [N police N] [Fn that [N Krueger N] [V [V& drove [P into [N the quarry N]P]V&] and [V+ never surfaced V+]V]Fn]V]

Each linguistic segment so far discussed has been well-behaved with respect to the basic document hierarchy, having only a single parent. Moreover, the segmentation has been complete, in that each part of the text is accounted for by some segment at each level of analysis, without discontinuities or overlap. This state of affairs does not of course apply in all types of analysis, and these Guidelines provide a number of mechanisms to support the representation of discontinuities or multiple analyses. A brief overview of these facilities is provided in chapter 20 Non-hierarchical Structures; also see 16 Linking, Segmentation, and Alignment. These mechanisms all depend to a greater or lesser degree on the use of pointing elements of various kinds.
