11. A system for identifying phrasal terms, the system comprising: a processor; and a memory, wherein the processor is configured to execute steps comprising: receiving a text having a plurality of words; determining a plurality of contexts, wherein a context comprises one or more words proximate to another word in the text; for each context, determining a first frequency based on a number of occurrences of the context within the text; assigning a first rank to at least one context based on the first frequency for the at least one context; determining multiple word-context pairs; for each word-context pair, determining a second frequency based on a number of occurrences of the word associated with the word-context pair being used in the context; assigning a second rank to at least one word-context pair based on the second frequency for the at least one word-context pair; determining a rank ratio for each word-context pair based on the first rank and the second rank associated with the word-context pair; determining a mutual rank ratio based on multiple rank ratios; and identifying a phrasal term based on the mutual rank ratio.
