He said he could tell when a query, worded the same way and submitted several times within a day or two, is a homework question.
Search engine users tend to write short queries, generally comprising of two or three query words.
If this feature is enabled, the lemma is also found for each of the query words.
Moreover, we also provide the statistical analysis of query words based on Amazon's Mechanical Turk (MTurk) crowdsourcing platform.
(3) The new query terms are reconstructed using of original query words and the weighting of medical terms. .
(3) Snippet scoring and selection Three scoring criteria were used to choose the most probable snippet including the target word used in the given word sense: (1) the word overlap between the example sentence and the snippet, (2) the number of adjacent query words to the target words in the snippet, and (3) the number of query words that appear in the snippet.
Search in the phoneme index takes place when the query word is an OOV or when it is forced by the user.
For a given query we denote by the set of relevant test sounds that are labeled with the query word, and as the number of relevant test sounds for that query.
For example, if a user enters a query and n keywords have been picked, then the best possible retrieval results will be the images whose descriptions contain all n query words.
There are approximately 63 k different phoneme trigrams in the final index, and the number of items exceeds 88 M. When searching the word index, all possible phonetic transcriptions (phoneme representations) of the query word are found in the lexicon.
Consequently, the set of query words is extended with all possible word forms found in the vocabulary for each of the lemmas (these linguistic processing steps are done using a method described in [27]).
