Simplified Process for Generating a Tech Forecast Reduced Database Data sources Acquisition/Feature Extraction Tech Monitoring Workstation Summarized, visualized information Query Instructions Arbitration Client Problem Definition Facilitation Team Web Based Facilitation System Forecast Forecast Expert Panel
Software Tools for Tech Forecasting • Gather and merge data • journal abstracts, patents, funding records, etc • Establish connections between data items • citations, common index terms, word co-occurrence • Interactively visualize data connections • enabling patents, critical technologies, indirect relations, etc • Interactively visualize technology trends • what’s fading, what’s coming in, what technology’s being borrowed from where.
OSU Database Information Visualization and Analysis Software (DIVA) • Automated construction of patent datasets from key patent lists • Generation of 2D maps and timelines using SOM neural network • Map visualization • dotmap, landscape, contour • Link visualization • similarity threshold, by cluster, precedent, dependent • Visualization of time trends • Cluster reports
Visualization Similarity Function Mapping Data Sources Project Database Clustering Indicators Reports CREATING AND EXPLORING A DOCUMENT DATABASE DOCUMENT SOURCES • US PATENTS • similarity function based on citations • ABSTRACTS • similarity function based on co-occurrence of terms • SCIENCE CITATION INDEX • similarity based on co-citation

Summarizing Document Cluster Data • Index terms or word occurrence frequency • helps label each cluster’s technical area • Author frequency table • identifies technology experts • Institution frequency table • identifies ‘centers of excellence’ • Graph of cluster document count vs. time • gives information about growth or decline of a specific technology • Table of links by cluster • gives information on which technologies are closely related • Graph of inter-cluster links vs time • gives information on cross-pollination of technology
‘Index Term’ frequency helps label clusters ‘Author Frequency’ identifies experts ‘Corporate Source’ frequency identifies centers of excellence
‘Emulsions/Water Pollution’ Cluster Graphs Flat volume of articles over time Increasing links to other emulsion technologies over time Emulsions – Water Pollution Links to ‘Hydration’ cluster peaks in 1998 Links to other clusters flat over time Question: Is there or was there an impending breakthrough in water pollution based on hydration? 14
CHEMICAL SENSORSDocument Sources • CHEMICAL ABSTRACTS • PATENTS • SCIENCE CITATION INDEX
Chemical SensorsApplications • Nerve agent, biological agent detection • Food spoilage detector • Drug screening • Genome imprinting • Synthetic antibodies • Molecular Imprinting
CHEMICAL SENSORS – PUBLICATION RATE DOCUMENTS PER YEAR YEAR
Similarity = 2*word co-occurence + 1*section co-occurence + 1*subsection co-occurence
Key Learnings – Chem Abstracts • Exponential rise in activity in last 10 years • Biological sensors most active • Large jumps in activity in 1992, 1995 • Large amount of Japanese, Swedish activity • Most active authors (experts) • Most active institutions (centers of excellence)
TOTAL PATENTS ISSUED PER YEAR Spike in 1992
Key Learnings - Patents • Time trends in patents • what caused spike in 1992? • Most active institutions • Most active inventors
