Abstract: It is intended to provide a polymer which is scarcely eluted, has a high biocompatibility and is useful in a filter for selectively eliminating leucocytes. It is also intended to provide a filter for selectively eliminating leucocytes, a filtration apparatus for selectively eliminating leucocytes and a system for selectively eliminating leucocytes, each having the above-described polymer. The above objects can be achieved by providing a polymer which comprises from 8% by mol to 45% by mol of a unit originating in a polymerizable monomer having a polyalkylene oxide chain, from 30% by mol to 90% by mol of a unit originating in a polymerizable monomer having a hydrophobic group, and from 2% by mol to 50% by mol of a unit originating in polymerizable monomer having a hydroxyl group.

Abstract: An automated natural language translation system takes source natural language text (preferably in Japanese) and translates them into a target natural language (preferably English). The system also allows an operator to re-translate automatically selected portions of the source text. The system includes an improvement directed to transforming kanas in the source text into alphabetic letters of the target language which allows the presence of a word or phrase boundary to be recognized in the middle of a kana. The system also includes an improvement involving performing concurrently on the source text both a morphological analysis and a syntactic analysis.

Abstract: Systems and methods for automated natural language translation take source natural language and translate it into a target natural language. The language translation is facilitated through the use of domain specific dictionaries, controlling grammar rules, and probability values associated with some dictionary entries. Domain specific dictionaries provide different translations of words depending on the context in which the words are used. Controlling grammar rules are used to supersede all other grammar rules to eliminate inaccurate and undesirable translations. Probability values are used to determine the likelihood a particular multi-word combination is a particular part of speech.

Abstract: Method and apparatus for automated natural language translation. Source language textual statements are stored in computer memory, and interpretations of source language textual statements are stored in a graph. An editing interface allows for the display of altered translations based on user input, and translation operations include semantic propagation based on stored grammar rules.
