2. Introduction intellectual innovator 1 • To better understand the R&D trends of wellbeing AI, we analyze a massive amount of patent data. • We use Panoramic View Analytics that is our unique data visualization method. • We show the main technology areas, growing and fusion areas, as well as the effectiveness of panoramic view analytics.
3. Methodology: Panoramic View Analytics intellectual innovator 2 Proven scientific methods that allows the user to “see and understand” the entirety of large amounts of data rather than “search and read” individual pieces of data. A B C Clustering docs by calculating similarities among them Visualization of the similarity among docs Original indicators for mining insights Patent / Paper / SNS / News / Annual Report etc Big Data Clustering Visualization Analytics
4. Methodology: Panoramic View Analytics intellectual innovator 3 We can get insights for strategy-making by analyzing information (distance, density, white space, distribution) on the radar chart. The size of each cluster is proportional to the number of documents in it. The distance between clusters indicates the similarities between them. The axis has no meanings. Each circle is called a “cluster”. They contain similar documents. Sparse area Density area Far = Low similarity Near = High similarity Figure 1: Understanding the Radar Chart.
5. Methodology: Algorithm intellectual innovator 4 Morphological analysis Extract characteristic word Calculating Similarities between Documents Visualization The system divides sentence into words. Calculating each word’s weight based on the term frequency and the inverse document frequency. e.g.) The words included in documents Doc.A：aaa | aaa | bbb | ccc Doc.B：aaa | bbb | bbb | ddd Doc.C：aaa | bbb | ddd | ddd Word TF IDF Weight (TF*IDF) aaa 2 1/3 2/3 bbb 1 1/3 1/3 ccc 1 1/1 1 Vectorizing each document based on the each word's weight, and calculating the similarities based on the inner product. Doc.A Vector aaa bbb ccc Doc.A Vector θ1 Doc.C Vector Doc.B Vector θ2 Visualizing by original algorithm based on Multi Dimensional Scaling method θ1 θ2 The system visualize the documents searched. Documents(1,2,3,…,n) Documents(1,2,3,…,n) The / system / visualize / the / documents / searched. Doc.A Doc.C Doc.B Doc.A Vector Doc.C Vector Doc.B Vector Word importance in Doc. A High-dimensional data representation (Tens of thousands) Modified MDS in order to express close relationship
6. Methodology: Patent Dataset of Analysis intellectual innovator 5 We made dataset S003 for analyzing Wellbeing /Healthcare and AI field. • Wellbeing / Healthcare: Keyword search • AI: IPC search (G06N) * IPC means International Patent Classification. And, G06N is “Computer systems based on specific computational models”. So, it is the IPC that represents the core technology area of AI. Also, it is used in JPO’s report on AI. No Content Search Type Search Formula Count (Rough estimate) S001 Wellbeing / Healthcare Keyword search “Wellbeing” OR “well-being” OR “happy” OR “happiness” OR “healthcare” // Title, Abstract, Claims 7,000 S002 AI IPC search G06N 14,000 S003 Total Logical expression S001 OR S002 21,000 Search condition DB： PatentSQUARE Period： Jan. 1, 2001 – Oct. 26, 2017 (publication date) Authority： US (published application) Language： English
