Self-information is calculated based on a probability of occurrence of the claim, where this probability is obtained from a language model. Grounded in information theory, this approach is based on the assumption that an unlikely concept is more informative than a usual concept, insofar as it is more surprising. In turn, the more surprising the information required to define the claim, the narrower its scope. Seven language models are considered, ranging from simplest models (each word or character has an identical probability) to intermediate models (based on average word or character frequencies), to large language models (LLMs) such as GPT2 and davinci-002. Remarkably, when using the simplest language models to compute the probabilities, the scope becomes proportional to the reciprocal of the number of words or characters involved in the claim, a metric already used in previous works. Application is made to multiple series of patent claims directed to distinct inventions, where each series consists of a set of claims having a gradually decreasing scope. The performance of the language models is then assessed through several ad hoc tests. The LLMs outperform models based on word and character frequencies, which themselves outdo the simplest models based on word or character counts. Interestingly, however, the character count appears to be a more reliable indicator than the word count.</div></div>","PeriodicalId":51794,"journal":{"name":"World Patent Information","volume":"79 ","pages":"Article 102321"},"PeriodicalIF":2.2,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142652739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A systematic coupling model was also built between patents and literature in this subject to compare and assess research states and hotspots. Our findings indicate that while the number of publications in the literature on microalgae bioreactors has been increasing, the number of patent applications has decreased since 2015. Literature on microalgae bioreactors primarily focuses on the use of different bioreactors to cultivate microalgae, treat wastewater, and generate biofuel. Meanwhile, patented technology research is mainly concentrated on the study and transformation of microorganisms and their components. The overall trend in this field shows a decreasing coupling degree, suggesting that the field of microalgae bioreactors has reached a mature stage and is currently experiencing a bottleneck period. This article utilizes a combination of literature visualization and patent analysis to identify technological gaps within the field of microalgae bioreactors. It provides guidance for the industrial development of microalgae biomass, and as such, is of great benefit in addressing the interdisciplinary challenges faced by researchers in this area.</div></div>","PeriodicalId":51794,"journal":{"name":"World Patent Information","volume":"79 ","pages":"Article 102319"},"PeriodicalIF":2.2,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142652736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
