Generation and Verification of a Hypothesis by Analogical Reasoning using Causal Relationships in Patent Documents - Life Science Fields as an Example -

Abstract

We applied analogical reasoning to causal relationship to generate hypotheses, and verified the hypotheses, as a basic study to develop a creativity support system. Causal relationships used in the present study have been extracted from patent documents of the field of pharmacy in our previous work, and consist of a term of method and a term of effect. Analogical reasoning is performed by replacing the term of the causal relationships with another similar term. Two hundred and twenty seven hypotheses are generated with analogical reasoning using the following 3 causal relationships; wound healing by peptide; anti-inflammatory by Magnolia bark; infection protecting activities by lactoferrin. As a result of verification of the 227 hypotheses by Life Science Dictionary, 91 hypotheses are appropriate as analogical reasoning. Furthermore, we verified 9 hypotheses among the 91 hypotheses with PubMed Central and PubMed, and found that 8 hypotheses have been reported in the literature. These results show that the hypotheses generated by analogical reasoning in the study are effective. patent documents, causal relationship, analogical reasoning, similarity, life sciences 論文

Novel liquid cobalt precursor for metal atomic layer deposition

“…In this experiment, the DIPRoBA-Co vaporization was carried out by the bubbling method. [21][22][23] The DIPRoBA-Co, which was heated in the liquid pot to 90 °C and bubbled by 10 sccm argon gas, was injected into the reaction chamber under 120 Pa total pressure, where the amount of DIPRoBA-Co introduced was calculated 23) from the ratio of [vapor pressure]/[total pressure] to be about 1 sccm. A substrate, constructed of 50 nm thick HTO (high-temperature deposited silicon dioxide) film on a silicon wafer, was set in the middle of the reaction chamber.…”
