Functions

• Download ontology from Github
• Read and convert ontology into CLOS object
• Build web-server with ontology

Installation

1. Install Homebrew

~ $ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

2. Install roswell via Homebrew (or Linuxbrew)

# (For Linux: You have to install linuxbrew at first. See [Linuxbrew installation](https://github.com/Linuxbrew))
# Install roswell via home(linux)brew
~ $ brew install roswell

# Ensure path to Photon binary in the Roswell Directory
~ $ echo "export PATH='$(HOME)/.roswell/bin':$PATH" >> ~/.profile

3. Install Photon from Github via Roswell

Editting Ontology by using developed Ontology Editors

• 法造(Hozo) - Ontology Editor

API for CommonLisp

API of Initialization

• Download ontology from github

CL-USER> (photon:install "dbym4820/ontologies/japanese-conversation/ontology3")

• Environment Initializer (Making .photon directory at home directory)

CL-USER> (photon:init)

• Converting Ontology

# ファイルパスの指定がなければ，デフォルトファイルを参照
CL-USER> (photon:convert-ontology "/path/to/xml")
("whole-root" ....)

API of Ontology Management

• Show all concepts in converted ontology

CL-USER> (photon:show-concepts)
("whole-root" ....)

• Show all concepts in converted ontology without instance concepts

CL-USER> (photon:show-all-class-concept)
("whole-root" ....)

• Show all instanced concepts in converted ontology

CL-USER> (photon:show-all-instance)
("some instance" ....)

• Get CLOS object of a concept from concept label

CL-USER> (photon:find-concept "concept-label")
#<PHOTON.ONTOLOGY::BASIC-CONCEPT #x302001FB00FD>

• 概念クラスの属性を調べる（部分概念や属性概念，それらの個数制約や概念名など）

CL-USER> (photon:concept-name (photon:parent-concept (photon:find-concept "concept-label")))
#<PHOTON.ONTOLOGY::BASIC-CONCEPT #x302001FB015D>

API of Web Server

• PhotonのWebサーバーのルーティングを書く

CL-USER> (photon:defphoton-route "/:arg" (params) (format nil "~A" (cdr (assoc 'arg :test #'string=))))

• PhotonのWebサーバーを立ち上げる・落とす

CL-USER> (photon:launch-gui :start-server 5000)
Hunchentoot server is started.
Listening on localhost:5000.

CL-USER> (photon:launch-gui :stop-server)
