  2. Projects Funded • CSIDM (CAS, China): Aobo, CSIDM Interns • ForeCite (Expires Oct 2010): Kaz, Emma, Thang Proposed • Data Cleaning in the Cloud (UCI) • Text Mining Clinical Articles (Duke-NUS / UCI) • Shreyasee, Justin, • Text Mining Scientific Articles (Global Asia Institute) • ForeCite2 WING, NUS

  3. DL IR/MM/HCI NLP Research Topics • Yee Fan Tan - Record Matching in Digital Libraries • Jin Zhao - Math Equation IR • Jesse Gozali – Phototaking Behavior • Ziheng Lin – Rhetorical Discourse Analysis • Cong Duy Vu Hoang – Related Work Summarization • Jun Ping Ng – Logic in Question Answering • Aobo Wang – Crowdsourcing for Machine Translation • Shihong Huang, Wai Hong Loh – Tooltip translator for Firefox • Kazunari Sugiyama - Recommender Systems in Digital Libraries • Minh Thang Luong – ForeCite • Emma Thuy Dung Nguyen – ForeCite Incoming Staff (4 UROP, 1 Intern): • Shomir Wilson (Intern) – Mention Detection in Scientific Articles, w/ Jin • Shawn Tan (UROP) – Continuing PARCELS, w/ Jesse • Tamisa Huangsiri, Low Wee Hung – (UROP) CSIDM Firefox w/ Aobo, Jun Ping • Yipeng Huang (UROP) – Cloud Data Cleaning, w/ Yee Fan, Jin WING, NUS

  4. Responsibilities (to be discussed) • Kaz: Non-CSIDM UROP guidance • Yee Fan: None (Thesis Writing!!) • Jin: RPNLPIR / Meeting and Room Bookings • Ziheng: Publication Page / Joomla / Social • Jesse: RoR / FC / CSX • Aobo: RoR / Web System Admin • Jun Ping: System Admin Lead WING, NUS

  5. Fixed IP CTE – RAID drive host, LDAP host, source code repository AYE – webserver, mailserver, mailman, virtual host on ECP DHCP (.ddns.) ECP – LDAP backup PIE – compute server Windows Server (.ddns) KPE KJE BKE SLE Cluster Architecture • Systems named after Singapore’s highways WING, NUS

  6. OS support All *nix group machines run CentOS 5 • stable Linux Enterprise distribution • all mount cte’s raid drive, plus other automounts Future • use rsync to sync all binaries across machines • expand RAID to encompass disks over different machines for more space (more SAN like) WING, NUS

  7. RAID setup • Currently 5.0 TB in RAID 5? • ext3 mounted to cte • /mnt/homes – home directories • /mnt/rpnlpir-indep – machine indep data (datasets) • /mnt/rpnlpir-Linux – binaries • /mnt/rpnlpir-Windows – binaries Future • DB server coming online for Rails applications WING, NUS

  8. Webserver (aye.comp.nus.edu.sg) • Apache • Virtual hosts (wing.comp, linc.comp, opac.comp) • Hosts Tomcat for java servlets • Hosts gmond (Gangila monitor) • Runs webalizer for stats • Hosts Ruby on Rails apps (Trung’s myror script; to be deprecated soon) • Hosts web service server (router for web service calls) WING, NUS

  9. Web Services • Our infrastructure tuned to make many services and demos by web services. • External calls to port 4000 • List of Webservices on http://wing.comp.nus.edu.sg/~forecite/ • Calls handled by WebServiceServer (WSS) ruby code. • Directory for webservices currently at /home/forecite/services/ WING, NUS

  10. Joomla • For our website • Administration by admin@wing, PhD students Customizations • Forum integration (phpbb) • Forum has contact information for all staff • Forum userdb not yet synched with shadow pass in LDAP • RPNLPIR (resource list) • Blog WING, NUS

  11. Mailing List • mailman run on aye • lists also run on wing (alias for aye) • both local and international mailing list hosted here WING, NUS

  12. LDAP • To keep logins/uids/guids synched • Main server on cte • Backup on aye • Needs to be robust in case of failure of LDAP server • Local root for all machines must be maintained WING, NUS

  13. RPNLPIR (Research Project for NLP / IR) • Common team account • Keep software repository mirrored by web page listing • Keeps CVS repo in ~/CVSDir • Keeps git repo in ~/repo • Accessible to all group members WING, NUS
