15. A system for determining and discerning items with multiple meanings in a sequence of items, the system comprising: a first distribution producing device configured to produce a distributed representation for each item of the sequence of items including a word vector and a context vector; a first partitioning device configured to partition the sequence of items into classes; a closeness determining device configured to calculate, using a representative word vector of each class, a cosine distance between the word vector and the class representative word vector; and a new sequence producing device configured to produce a new sequence of items by modifying the distributed representation in the producing by replacing each occurrence of an item in the distributed representation having a largest cosine distance between the word vector and the class representative vector calculated by the calculating; and wherein the producing the new sequence produces the new sequence by replacing each word occurrence in the input sequence of items by w_i, where i comprises the class index among closest classes that the cosine distance of the representative context vector of the class is closest to an average word vector for the items in a window around the item.

The system of claim 15 , further comprising a second distribution representation producing device configured to produce a new distributed representation for the new sequence of items produced in the producing the new sequence of items.
