Patent ID: 7072827

Claim:
A method for morphological disambiguation, comprising: building a statistical base by morphologically analyzing a corpus of text comprising multiple words having lemmas so as to find respective linguistic patterns of the words independently of the lemmas to which the linguistic patterns are applied, each pattern comprising a specification of at least one characteristic selected from a set of characteristics including a part of speech, prefix, number, gender and person, and finding relative frequencies of occurrence of the linguistic patterns in the corpus; receiving an input string; morphologically analyzing the string to generate a list of candidate analyses of the string, each candidate analysis comprising a respective word, having a linguistic pattern and a lemma; and evaluating the pattern in each of the analyses using the statistical base so as to determine a relative frequency of occurrence of the pattern in each of the analyses, independent of the lemma to which the pattern is applied; and selecting from the list one or more of the analyses that comprise respective patterns whose frequency of occurrence is above a predetermined threshold.
