Abstract

Information extraction from domain-specific documents can include performing named entity recognition thereon. A regular expression tagger can tag regular expressions in the domain-specific documents without pre-annotated training sets for the regular expression tagger. Defined domain-specific terms can be augmented with terms and phrases related to the defined domain-specific terms based on rules specified for desired information about named entities to be extracted. A dictionary-based tagger can tag the defined and augmented domain-specific terms and phrases in the plurality of domain-specific documents. Conflicts of named entity recognition between the regular expression tagger and the dictionary-based tagger can be resolved. The desired information about named entities can be extracted. Classification can be performed to identify whether the domain-specific documents are related to the desired information.

Abstract

The present disclosure provides a process. In an embodiment, the process includes providing pellets of a recycled non-virgin material. The recycled nonvirgin material is formed from a multilayer structure that is composed of at least (i) a layer composed of an olefin-based polymer, and (ii) an adhesive layer. The adhesive layer is composed of a solvent-based adhesive composition. The process includes blending the pellets with an olefin-based polymer blend component to form a blended material and forming the blended material into an article.
