Twenty years of US nanopatenting: Maintenance renewal scoring as an indicator of patent value (FULL-TEXT)

This paper introduces a new measure of patent value – Maintenance Renewal Score (MRSc) – reflecting assignee valuing the patent by paying successive renewal fees. We generate MRSc’s for nanotechnology patents issued by the US Patent Office from 1999 through 2009, with US assignees and US inventors. Patenting increases over this period, coincident with increased…
Research on Correlation Control of Subjective Patent Indicators Based on Progressive Constraint

Abstract Patent indicator evaluation is a relatively objective patent quality evaluation method recognized by academia. Some subjective patent indicators are often related, which to some extent interferes with the objectivity of patent evaluation. This study selects five commonly used subjective patent indicators that are directly related to the compilers of patent documents, which includes patent…
Different approaches of bibliometric analysis for data analytics applications in non-profit organisations (FULL-TEXT)

Profitable companies that used data analytics have a double gain in cost reduction, demand prediction, and decision-making. However, using data analysis in non-profit organisations (NPOs) can help understand and identify more patterns of donors, volunteers, and anticipated future cash, gifts, and grants. This article presents a bibliometric study of 2673 to discover the use of…
A hybrid approach to identify and forecast technological opportunities based on topic modeling and sentiment analysis (Full-Text)

The spring up of new & emerging technologies brings a lot of innovation opportunities for society, which enables technology opportunities analysis attracts increasing attention by both industry and academia recently. This study proposes a hybrid approach which integrates topic modeling, sentiment analysis, patent mining and expert judgment to identify technological topics and the potential development…
Technological Emergence and Military Technology Innovation

To what extent is military technology innovation emergent? This study answers this question by applying an emergence detection algorithm to roughly 300,000 technical terms extracted from military technology patents granted from 1980 to 2019. Emergence – instances of sudden and rapid growth of a technical term within the military patent corpus – is found to…
Integrative model for discovering linked topics in science and technology

Highlights• The science and technology semantic linkage integration model improves the identification of linked topics in science and technology (LTSTs). • Simple fusion and link prediction form a twofold model to identify topics and implicit semantics. • Term co-occurrence networks of basic and applied research are fused. • The fusion expands topic networks and enhances…
Combining topic modeling and SAO semantic analysis to identify technological opportunities of emerging technologies

A hybrid approach to extract technical intelligence for technological opportunities analysis. To blend topic modeling, SAO semantic analysis and machine learning. An optimized LDA-based topic extraction model with high accuracy. A case study on dye-sensitized solar cell. With the advancement of science and the emergence of new technologies, technology opportunities analysis has attracted increasing attention…
Identification of topic evolution: network analytics with piecewise linear representation and word embedding

Understanding the evolutionary relationships among scientific topics and learning the evolutionary process of innovations is a crucial issue for strategic decision makers in governments, firms and funding agencies when they carry out forward-looking research activities. However, traditional co-word network analysis on topic identification cannot effectively excavate semantic relationship from the context, and fixed time window…
Mapping technological innovation dynamics in artificial intelligence domains: Evidence from a global patent analysis (full-text)

Artificial intelligence (AI) is emerging as a technology at the center of many political, economic, and societal debates. This paper formulates a new AI patent search strategy and applies this to provide a landscape analysis of AI innovation dynamics and technology evolution. The paper uses patent analyses, network analyses, and source path link count algorithms…
Common contributing factors to COVID-19 and inflammatory bowel disease (full-text)

The devastating complications of coronavirus disease 2019 (COVID-19) result from an individual’s dysfunctional immune response following the initial severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Multiple toxic stressors and behaviors contribute to underlying immune system dysfunction. SARS-CoV-2 exploits the dysfunctional immune system to trigger a chain of events ultimately leading to COVID-19. We have…
