Chemical patents contain detailed information on novel chemical compounds that is valuable to the chemical and pharmaceutical industries. In this paper, we introduce a system, NERChem that can recognize chemical named entity mentions in chemical patents. NERChem is based on the conditional random fields model (CRF). Our approach incorporates (1) class composition, which is used for combining ch...

this paper tries to survey irans regional labor market disequilibrium within 1996-2000. according to the results there has been an increase in the amount of disequilibrium of irans national as well as regional labor markets. incomplete labor market information on vacant job opportunities in different regions of the country along with high costs of migration have been the major causes of unemplo...

In response to growing needs for cross-lingual patent retrieval, we propose PRIME (Patent Retrieval In Multilingual Environment system), in which users can retrieve and browse patents in foreign languages only by their native language. PRIME translates a query in the user language into the target language, retrieves patents relevant to the query, and translates retrieved patents into the user l...

Patents' search is increasingly critical for a company's technological advancement and sustainable marketing strategy. When most innovative designs are created collaboratively by a diverse team of researchers and technologists, patent knowledge management becomes time consuming with repeated efforts creating additional task conflicts. This research develops an intelligent recommendation methodo...

In this paper we describe experiments conducted for CLEFIP 2011 Prior Art Retrieval track. We examined the impact of 1) using key phrase extraction to generate queries from input patent and 2) the use of citation network and (International Patent Classification) IPC class vector in ranking patents. Variations of a popular key phrase extraction technique were explored for extracting and scoring ...

Introduction This paper presents an analysis of knowledge flows in the pharmaceutical innovation process. Backward citations, citations to non-patent literature (NPL), and forward citations that link patents, scientific publications, and pharmaceutical pipelines data on drug developments are analyzed and visualized to provide a more holistic understanding. Results show that patents linked to dr...

Patents have great public visibility these days; questions and opinions abound on the fairness of the patent system, the validity of large amount of patents, and the rights of the “haves” versus the “have nots”. There are questions around the fundamental nature of the patent system – whether patents are protecting and fostering innovation, or whether they have begun to hurt innovation. In this ...

Australia, like most countries, faces high and rapidly-rising drug costs. There are longstanding concerns about pharmaceutical companies inappropriately extending their monopoly position by "evergreening" blockbuster drugs, through misuse of the patent system. There is, however, very little empirical information about this behaviour. We fill the gap by analysing all of the patents associated wi...
