!Research Interests
My major research interests are information retrieval, and how to use compuational linguistic methods or other techniques to improve the effectiveness and performance of IR.

In the information retrieval field, the situation where the words in a query might not appear in a document, despite it being relevant to the query is common, as revealed by the early experiment at the University of Pennsylvania, which found that only 11 out of 23 documents properly indexed under the subject toxicity had any use of a word containing the stem toxi [Connor 1961]. Based on the work in the late 1950, Swanson concluded that to anticipate the words that would be used in a document to express the idea in a search question was as difficult in practice as it was in principle [Swanson 1988]. And this problem has already been pointed out at the International Conference on Scientific Information (ICSI) in 1958 by Vic Yngve [Yngve 1959]. His insights on the ubiquity of ambiguity and on the need to find “formal connections between widely divergent ways of saying essentially the same thing” must be considered prophetic. In 1985, Blair and Maron corroborated these basic difficulties, offered an illuminating discussion of their nature and causes for specific types of search questions, and made a similar statement [Blair and Maron 1985].

Addressing such problem, users usually need to manually refine a query themselves. However, a system can also help with query refinement either fully automatically or with the user in the loop. The methods can be split into two major classes: global methods and local methods [Manning, Raghavan, and Schutze 2008].

Global methods—techniques for expanding or reformulating query terms independent of the query results, so that changes in the query wording will cause the new query to match other semantically similar terms. Global methods include:
*Query expansion/ reformulation with a thesaurus or WordNet
*Query expansion via automatic thesaurus generation
*Techniques like spelling correction

Local methods—adjust a query relative to the documents that initially appear to match the query. The basic methods here are:
*Relevance feedback, also known as explicit relevance feedback
*Pseudo-relevance feedback, also known as Blind relevance feedback
*(Global) indirect relevance feedback, also known as implicit relevance feedback

Overall, I would like to explore the problems related to automatic thesaurus generation, and make use of this research result to help users expanding or reformulating their query terms, such that to improve their experience of using IR system.

Overview
The lexical bookmarking system is envisioned as a component of larger systems, such as knowledge management systems and productivity tools. It will allow the these system to identify and return to specific passages of any length in specific documents in a corpus using Information Retrieval (IR) algorithms. Other possible components of such a system could tools for classifying the bookmarked documents and passages and organizing them in research/writing projects.

The bookmark system works in conjunction with a search engine. It uses an algorithm that builds a highly reliable search and stores it. When this lexical bookmark is submitted to search engine as a query, it functions as a document identifier and a durable pointer to any passage in any document.

The system will not not rely on document identifiers, bibliographic metadata, or position coordinates. It will not alter the documents in any way. Instead, it will generate and store a query based on the text in the document that will (a) identify the correct document and (b) locate the desired passage with recall and precision rates close to 100%. In this system it should be be possible to delete a document from the corpus and replace it with another copy or even a later version of the document without breaking the bookmarks.

Because the lexical bookmark system is independent of document metadata, it is suitable to use with document collections where there is no practical way to impose durable document IDs or standard field definitions. Possible applications inlcude ad hoc collections created in a personal or corporate knowledge base. It is conceivable that the system could be make to work with proprietary databases.

* The "display one tiddler at a time" option can also be //temporarily// set/reset by including a 'paramifier' in the document URL: {{{#SPM:true}}} or {{{#SPM:false}}}.
* If more than one display mode is selected, 'one at a time' display takes precedence over both 'top' and 'bottom' settings, and if 'one at a time' setting is not used, 'top of page' takes precedence over 'bottom of page'.
* When using Apple's Safari browser, automatically setting the permalink causes an error and is disabled.

|Description|Documentation for SinglePageModePlugin|
Normally, as you click on the links in TiddlyWiki, more and more tiddlers are displayed on the page. The order of this tiddler display depends upon when and where you have clicked. Some people like this non-linear method of reading the document, while others have reported that when many tiddlers have been opened, it can get somewhat confusing.  SinglePageModePlugin allows you to configure TiddlyWiki to navigate more like a traditional multipage web site with only one item displayed at a time.
!!!!!Usage
<<<
When the plugin is enabled, only one tiddler will be displayed at a time and the browser window's titlebar is updated to include the current tiddler title.  The browser's location URL is also updated with a 'permalink' for the current tiddler so that it is easier to create a browser 'bookmark' for the current tiddler.  Alternatively, even when displaying multiple tiddlers //is// permitted, you can still reduce the potential for confusion by forcing  tiddlers to always open at the top (or bottom) of the page instead of being displayed following the tiddler containing the link that was clicked.
<<<
!!!!!Configuration
<<<
<<option chkSinglePageMode>> Display one tiddler at a time
><<option chkSinglePageKeepFoldedTiddlers>> Don't auto-close folded tiddlers
><<option chkSinglePagePermalink>> Automatically permalink current tiddler
<<option chkTopOfPageMode>> Always open tiddlers at the top of the page
<<option chkBottomOfPageMode>> Always open tiddlers at the bottom of the page
<<option chkSinglePageAutoScroll>> Automatically scroll tiddler into view (if needed)

Notes:
* {{block{
The "display one tiddler at a time" option can also be //temporarily// set/reset by including a 'paramifier' in the document URL: {{{#SPM:true}}} or {{{#SPM:false}}}. You can also use {{{SPM:expression}}}, where 'expression' is any javascript statement that evaluates to true or false.  This allows you to create hard-coded links in other documents that can selectively enable/disable the use of this option based on various programmatic conditions, such as the current username. For example, using
&nbsp;&nbsp;&nbsp;{{{#SPM:config.options.txtUserName!="SomeName"}}}
enables 'one tiddler at a time' display for all users //other than// "~SomeName")}}}
* If more than one display mode is selected, 'one at a time' display takes precedence over both 'top' and 'bottom' settings, and if 'one at a time' setting is not used, 'top of page' takes precedence over 'bottom of page'.
* When using Apple's Safari browser, automatically setting the permalink causes an error and is disabled.

<<<
2008.04.08 [2.9.1] don't automatically add options to AdvancedOptions shadow tiddler
2008.04.02 [2.9.0] in displayTiddler(), when single-page mode is in use and a tiddler is being edited, ask for permission to save-and-close that tiddler, instead of just leaving it open.
2008.03.29 [2.8.3] in displayTiddler(), get title from tiddler object (if needed).  Fixes errors caused when calling function passes a tiddler *object* instead of a tiddler *title*
2008.03.14 [2.8.2] in displayTiddler(), if editing specified tiddler, just move it to top/bottom of story *without* re-rendering (prevents discard of partial edits).
2008.03.06 [2.8.1] in paramifier handler, start 'checkURL' timer if chkSinglePageMode is enabled
2008.03.06 [2.8.0] added option, {{{config.options.chkSinglePageKeepFoldedTiddlers}}}, so folded tiddlers won't be closed when using single-page mode.  Also, in checkURL(), if hash is a ''permaview'' (e.g., "#foo bar baz"), then display multiple tiddlers rather than attempting to display "foo bar baz" as a single tiddler
2008.03.05 [2.7.0] added support for "SPM:" URL paramifier
2008.03.01 [2.6.0] in hijack of displayTiddler(), added 'title' argument to closeAllTiddlers() so that target tiddler isn't closed-and-reopened if it was already displayed.  Also, added config.options.chkSinglePageAutoScrolloption to bypass automatic 'scroll into view' logic (note: core still does it's own ensureVisible() handling)
2007.12.22 [2.5.3] in checkLastURL(), use decodeURIComponent() instead of decodeURI so that tiddler titles with commas (and/or other punctuation) are correctly handled.
2007.10.26 [2.5.2] documentation cleanup
2007.10.08 [2.5.1] in displayTiddler(), when using single-page or top-of-page mode, scrollTo(0,0) to ensure that page header is in view.
2007.09.13 [2.5.0] for TPM/BPM modes, don't force tiddler to redisplay if already shown.  Allows transition between view/edit or collapsed/view templates, without repositioning displayed tiddler.
2007.09.12 [2.4.0] added option to disable automatic permalink feature.  Also, Safari is now excluded from permalinking action to avoid bug where tiddlers don't display after hash is updated.
2007.03.03 [2.3.1] fix typo when adding BPM option to AdvancedOptions (prevented checkbox from appearing)
2007.03.03 [2.3.0] added support for BottomOfPageMode (BPM) based on request from DaveGarbutt
2007.02.06 [2.2.3] in Story.prototype.displayTiddler(), use convertUnicodeToUTF8() for correct I18N string handling when creating URL hash string from tiddler title (based on bug report from BidiX)
2007.01.08 [2.2.2] use apply() to invoke hijacked core functions
2006.07.04 [2.2.1] in hijack for displayTiddlers(), suspend TPM as well as SPM so that DefaultTiddlers displays in the correct order.
2006.06.01 [2.2.0] added chkTopOfPageMode (TPM) handling
2006.02.04 [2.1.1] moved global variable declarations to config.* to avoid FireFox 1.5.0.1 crash bug when assigning to globals
2005.12.27 [2.1.0] hijack displayTiddlers() so that SPM can be suspended during startup while displaying the DefaultTiddlers (or #hash list).  Also, corrected initialization for undefined SPM flag to "false", so default behavior is to display multiple tiddlers
2005.12.27 [2.0.0] Update for TW2.0
2005.11.24 [1.1.2] When the back and forward buttons are used, the page now changes to match the URL.  Based on code added by Clint Checketts
2005.10.14 [1.1.1] permalink creation now calls encodeTiddlyLink() to handle tiddler titles with spaces in them
2005.10.14 [1.1.0] added automatic setting of window title and location bar ('auto-permalink').  feature suggestion by David Dickens.
2005.10.09 [1.0.1] combined documentation and code in a single tiddler
2005.08.15 [1.0.0] Initial Release
