He withdrew and Herbert Coleridge became the first editor. His house was the first editorial office. He arrayed , quotation slips in a 54 pigeon-hole grid. Furthermore, many of the slips were misplaced. Furnivall believed that, since many printed texts from earlier centuries were not readily available, it would be impossible for volunteers to efficiently locate the quotations that the dictionary needed.
As a result, he founded the Early English Text Society in and the Chaucer Society in to publish old manuscripts. Furnivall recruited more than volunteers to read these texts and record quotations.
While enthusiastic, the volunteers were not well trained and often made inconsistent and arbitrary selections.
Ultimately, Furnivall handed over nearly two tons of quotation slips and other materials to his successor. He then approached James Murray , who accepted the post of editor. In the late s, Furnivall and Murray met with several publishers about publishing the dictionary. In , Oxford University Press agreed with Murray to proceed with the massive project; the agreement was formalized the following year. It was another 50 years before the entire dictionary was complete.
Late in his editorship, Murray learned that a prolific reader named W. Minor was a criminal lunatic. Minor invented his own quotation-tracking system, allowing him to submit slips on specific words in response to editors' requests. Oxford editors[ edit ] James Murray in the Scriptorium at Banbury Road During the s, the Philological Society was concerned with the process of publishing a dictionary with such an immense scope. The OUP finally agreed in after two years of negotiating by Sweet, Furnivall, and Murray to publish the dictionary and to pay Murray, who was both the editor and the Philological Society president.
The dictionary was to be published as interval fascicles, with the final form in four volumes, totalling 6, pages. They hoped to finish the project in ten years.
For instance, there were ten times as many quotations for abusion as for abuse. Accordingly, new assistants were hired and two new demands were made on Murray. Murray had his Scriptorium re-erected on his new property. Murray did not want to share the work, feeling that he would accelerate his work pace with experience.
In , Bradley moved to Oxford University. Newspapers reported the harassment, particularly the Saturday Review , and public opinion backed the editors.
If the editors felt that the dictionary would have to grow larger, it would; it was an important work, and worth the time and money to properly finish. Neither Murray nor Bradley lived to see it. These methods do not guarantee finding the collocations if they do not have sufficiently high frequency. Usually, the great number of collocations does not have this frequency.
Besides, the corpus size for such search should be larger than the existing corpora now measured in gigabytes. There are several attempts to apply the results of automatic syntactic analysis parsing for compilation of dictionaries of collocations [3, 7].
For example, in a recent work Strzalkowski  uses the syntactic analysis for improving results of information retrieval by enriching the query. One of the classic works on the theme is . The system Xtract is presented that allows for finding repeated co-occurrences of words based on their mutual information. The work consists in three stages, and, at the third stage, the partial syntactic analysis is used for filtering out the pairs that do not have a syntactic relation.
Unfortunately, all these methods are applied to word pairs obtained by frequency analysis using a threshold. The aim of all these methods is collocations, and not free word combinations see below. There are already some resources of the described type available.
One of the largest dictionaries of collocations and free word combinations is CrossLexica system [4, 5, 6]. It contains about , word combinations for Russian with semantic relations between the words and the possibilities of inference. There is also this type of resources for the English language, e.
This is the lower bound of the dictionary of word combinations, which justifies the term very large dictionary in the title of this paper.
In the rest of the paper, we first discuss the concept of collocation and its relation with free word combination, and then we describe the method of enrichment of the dictionary based on automatic syntactic analysis with dependency representation. After this, we evaluate its performance, and finally draw some conclusions. Intuitively, collocation is a combination of words that has certain tendency to be used together.
Still, the strength of this tendency is different for different combinations. Thus, collocations can be thought of as a scale with different grades of strength of the inter-word relation, from idioms to free word combinations. In this case, the meaning of the whole is not related with the meaning of the components. In certain much more rare cases, the meaning of the whole has the relation with the meaning of the components, but also it has an additional part that cannot be inferred, e. In this case, the meaning of the whole is directly related only with one word in the example above, the word attention , while the other word expresses a certain standard semantic relation between actants of the situation.
Usually, for a given semantic relation and for a given word that should conserve its meaning, there is a unique way to choose the word for expressing the relation in a given language. The degree of freedom depends on how many words can be used as substitutes of each word.
Unfortunately, till now they are not reflected systematically even in good dictionaries. This is because the work of finding these functions is rather laborious and it needs very high-level lexicographic competence. Another important point is that some free word combinations can have associative relations between its members, e. This makes some combinations more idiomatic because the inter-word relation is strengthened by association.
Since there is no obvious border between more idiomatic and less idiomatic, the concept of collocation finally can cover all free word combinations as well, though this makes this concept useless because its purpose is to distinguished idiomatic word combinations from the free ones.
Thus, in our opinion, the difficulties related with the concept of collocations are related with impossibility to draw the exact border between it and free word combinations. Note that the obvious solution to treat collocations only as lexical functions contradicts to the common practice.
This demonstrates that, in any case, we need something to distinguish between more and less idiomatic free word combinations. If it is not collocation, then the other term should be invented.
For example, in automatic translation, some wrong hypothesis can be eliminated using the context ; in language learning, the possibility to know the compatibility allows for much better comprehension of a word; not speaking about automatic word sense disambiguation, where one of the leading approaches is analysis of the context for searching of the compatible words, etc.
Note that manual compilation or enrichment of the dictionary of free word combinations is very time-consuming, for example, CrossLexica  was being complied during more than 13 years and it is very far fromcompletion yet. We suggest the following method of automatic enrichment of such kind of dictionaries. Obviously, the method needs some post-verification, because we cannot guarantee the total correctness of the automatic syntactic analysis, still, it is much more efficient than to do it manually.
We work with the Spanish language, but the method is easily applicable for any other language depending on the availability of a grammar and a parser. First, we apply the automatic syntactic analysis using the parser and the grammar of Spanish developed in our laboratory .
The results of the syntactic analysis are represented using the formalism of dependencies .
The idea of the formalism of dependencies is that any word has dependency relations with the other words in a sentence. The relations are associated directly with word pairs, so it is not necessary to pass the constituency tree in order to obtain the relation.
One word always is a head of relation, and the other one is its dependant. Obviously, one headword can have several dependencies. The problems that are to be solved even using this formalism are the treatment of coordination conjunctions and prepositions, and filtering of some types of relations and some types of nodes pronouns, articles, etc.
We store the obtained combinations in the database. All members of the pairs are normalized. Still, some information about the form of the dependant is saved also. The coordinative conjunctions are heads in the coordinative relation; still, the word combinations that should be added to the dictionary are the combinations with their dependants.
For example, I read a book and a letter, the combinations that should be extracted are read book and read letter. Thus, the algorithm detects this situation and generates two virtual combinations that are added to the dictionary. Treatment of prepositional relation is different from other relations.
Since the prepositions usually express grammar relations between words for example, in other languages these relations can be expressed by grammar cases , the important relation is not relation with the preposition, but the relations between two lexical units connected by the preposition.
Still, the preposition itself is also of linguistic interest, so we reflect this relation in the dictionary by the word combination that contains three members: Filtering of determined types of nodes is very easy. Since the parser uses the automatic morphological analysis, the morphological information for every word is available. It allows for filtering out the combinations without significant lexical contents , i. The following categories are discarded in the actual version of the algorithm: These combinations are of no interest for the dictionary under consideration.
The other filter is for the types of relations. It depends on the grammar that is used. In our grammar, the following relations are present: Among these relations, the prepositional and coordinative are treated in a special mode, as mentioned above. The only relations left that are of no use for detecting of word combinations are subordinate relation and circumstantial relation.
One of the advantages of the suggested method is that it does not need corpus for its functioning, and, thus, there is no dependency of the corpus size or corpus lexical structure. Let us have a look at the example of the functioning of the method.
The following sentence is automatically parsed. I knew all detours of the river and its mysteries. The following dependency tree corresponds to this sentence.
The hierarchy of depth in the tree corresponds to the relations number of spaces at the beginning of each line2. Each line corresponds to a word and contains the word form and its lemma, e.
The following word combinations were detected: The preposition del is part of the 3-member word combination. The articles and pronouns are filtered out el, todo, su , though the algorithm found the corresponding word combinations.
Totally 60 sentences were parsed that contain words, 2 Usually, the arrows are used to show the dependencies between words, but it is uncomfortable to work with arrows in text files, so we use this method of representation.
Besides, this representation is much more similar to constituency formalism. For evaluation, we manually marked all dependency relations in the sentences.
Then we compared the automatically added word combinations with manually marked word combinations. Apart, we used as a baseline a method of gathering the word combinations that takes all word pairs that are immediate neighbors. Also we added certain intelligence to this baseline method — it ignores the articles and takes into account the prepositions.
The following results were obtained. The total number of correct manually marked word combinations is From these, word combinations were found by our method. At the same time, the baseline method found correctly word combinations. These numbers give us the following values of precision and recall.
Let us remind that precision is the relation of the correctly found to totally found, while the recall is the relation of the correctly found to the total that should have been found. It is obvious that precision of our method is much better and recall is better than these parameters of the baseline method.
Still, compiling and enriching of this dictionary manually is too time and effort consuming task. We proposed a method that allow for enrichment of such dictionary semi- automatically.
