Hakia - The semantic search engine hakia - °Ë»ö ¿£ÁøÀ» ÀǹÌ

Semantic search engines are making a buzz lately.  Google, even with its own power and might of searching webpages, is one of the challenged search engines who don¡¯t employ semantics on its rule to determine page relevance. ¹öÁî´Â ÃÖ±Ù¿¡ °Ë»ö ¿£ÁøÀ» ¸¸µå´Â ÀǹÌÇÕ´Ï´Ù. ±¸±Û, ½ÉÁö¾î ÀÚ½ÅÀÇ ÆÄ¿ö¿Í À§·ÂÀ» °Ë»ö°ú À¥ÆäÀÌÁö,ÀÌ Áß Çϳª¸¦ °Ë»ö ¿£Áø¿¡ Àå¾ÖÀÎÀ» °í¿ëÇÏÁö ´©±¸ÀÇ Áö¹è¸¦ È®ÀÎ ÆäÀÌÁö¿¡ °ü·Ã¼ºÀÌ ÀǹÌÇÕ´Ï´Ù. Unlike ´Þ¸®

Google who uses page ranking algorithms to determine if your searched phrase matches a webpage, Hakia uses a semantic approach to determine if your keywords are related to a webpage even if the keywords are not in the webpage.  Sound confusing?

It is at first. ±×°ÍÀº ¿ì¼±ÇÕ´Ï´Ù. With semantics, the search engine should be able to find related pages to the keyword by intelligently matching your keyword with related words. °ú Àǹ̷Ð, °Ë»ö ¿£Áø¿¡¼­ °ü·Ã ÆäÀÌÁö¸¦ ãÀ» ¼ö ÀÖ¾î¾ßÇÕ´Ï´Ù¿Í ÀÏÄ¡Çϴ Ű¿öµå¸¦ Ű¿öµå¿Í °ü·Ã ´Ü¾î¸¦ Áö´ÉÀûÀ¸·ÎÇÕ´Ï´Ù.

If you are searching for ¡°basketball¡± for example, the web pages containing ¡°NBA¡±, ¡°Michael Jordan¡±, ¡°Yao Ming¡± or ¡°John Stockton¡± should appear even if they did not mention basketball in the webpage itself. °Ë»öÇÏ´Â °æ¿ì¿¡´Â "³ó±¸"¿¹¸¦ µé¾î, À¥ ÆäÀÌÁö¸¦ Æ÷ÇÔÇÏ´Â "nba", "¸¶ÀÌŬ Á¶´ø", "¾ß¿À¹Ö"¶Ç´Â "Á¸ ½ºÅ¹ÅÏ"ÀÌ ³ªÅ¸³³´Ï´Ù ³ó±¸¿¡ ´ëÇØ¼­´Â ¾ð±ÞÇÏÁö ¾Ê¾Ò´ÙÇÏ´õ¶óµµ À¥ ÆäÀÌÁö¸¦ ÀÚ½ÅÇÕ´Ï´Ù.

Hakia hakia encourages a conversational type of searching maybe to help the semantic engine determine the best match for your query.  The queries should be in question form so I tried ¡°Who is the greatest basketball player?¡± and it was right on the spot: ´ëÈ­ Çü½ÄÀÇ Àå·Á¿¡ µµ¿òÀÌ ¾î¼¸é Àǹ̸¦ °Ë»ö ¿£Áø¿¡ °Ë»ö¾î¿¡ ÀÏÄ¡ÇÏ´Â ÃÖ°íÀÇ °áÁ¤ÇÕ´Ï´Ù.ÇÏ´Â Äõ¸® Áú¹® ¾ç½Ä¿¡ ÀÖ¾î¾ß ±×·¡¼­ ³­ ½Ãµµ "´©±¸´Â ÃÖ°íÀÇ ³ó±¸ ¼±¼ö?"±×¸®°í ±×°Ç ¹Ù·Î ½ºÆ÷Æ® :

The answer is in conversational type too and it suggests a gallery for ¡°Basketball¡± which is a functionality offered by it¡¯s capability to determine the related wider topic to the question asked.  The ¡°see this page¡± links to NBA.com¡¯s article with MJ. ±×¸®°í ±×°ÍÀº ´ëÈ­ÀÇ Çü½Ä¿¡ ´ëÇÑ ´äº¯µµ Á¦½Ã °¶·¯¸®¿¡¼­ "³ó±¸"À̰ÍÀº ±×°ÍÀÇ ´É·ÂÀ» È®ÀÎÇÏ´Â ±â´ÉÀ» Á¦°øÇÏ´Â °ü·Ã ´Ù¾çÇÑ ÁÖÁ¦¸¦ ¹¯´Â Áú¹®À»ÇÕ´Ï´Ù.¿¡¼­ "ÀÌ ÆäÀÌÁö¸¦ º¼"¸µÅ©¸¦ nba.com ´ÔÀÇ ±â»ç¿Í ¿¥Á¦ÀÌÇÕ´Ï´Ù.

Another feature of Hakia is that it gets snippets of the webpage and then highlighting the relevant entry for easier viewing: ¶Ç ´Ù¸¥ ±â´ÉÀ» hakia°¡¿¡ µµ´ÞÇÏ°í ´ÙÀ½À» °­Á¶ÇÏ´Â À¥ ÆäÀÌÁöÀÇ ³»¿ë ¹Ì¸®º¸±âÀÇ °ü·Ã Ç׸ñÀ» ½±°Ôº¸°í :

Now, Hakia seems to be on the spot if asked the right question but it could easily lead to a disaster if not used properly.  To demonstrate let¡¯s try ¡°who is the greatest drummer¡±: Áö±Ý, hakia °Í °°½À´Ï´Ù ¹°¾úÀ» °æ¿ì ±× ÀÚ¸®¿¡¼­ ¹Ù·Î Áú¹®À»ÇÏ°í ½ÍÁö¸¸ ½±°Ô ÀûÀýÇÏ°Ô »ç¿ëÇÏÁö ¾Ê´Â °æ¿ì¿¡´Â ÀçÇØ°¡ ¹ß»ý ÇÒ °ÍÀÌ´Ù. º¸´Â°Ô ÇØº¸ÀÚ "´©±¸´Â ÃÖ°íÀÇ µå·¯¸Ó":

The answer was totally not what I expected.  Since it sees a poetry website with phrases containing the ¡°The Greatest Drummer¡± but it was right on the category of drums and percussion. ±â´ëÇß´ø °Í°ú¿¡ ´ëÇÑ ´äº¯Àº ÀüÇô¾ø½À´Ï´Ù.

I adjusted my query to ¡°who is the greatest rock drummer¡± and then it started to make sense: ³ª´Â ³» Äõ¸®¸¦ Á¶Á¤ "´©±¸´Â ÃÖ°íÀÇ ·Ï µå·¯¸Ó"±×¸®°í, ±×°ÍÀ» ÀÌÇØÇϱ⠽ÃÀÛ :

Neil Peart? ´Ò peart? Hmm, that is debatable, but since now it gives me a real drummer as an answer to ¡°consider¡± then I think I could be more forgiving.  I tried to ask ¡°who is the Beatles¡¯ drummer?¡± and it gave me ¡° Èì, ±×°ÍÀº ÇÏ»ç°ü,ÇÏÁö¸¸ ½ÇÁ¦ µå·¯¸Ó·ÎºÎÅÍ Áö±Ý¿¡ ´ëÇÑ ´äº¯À» ÁØ´Ù "°í·Á"±×·³ ³­ ÇÒ ¼öÀÖÀ» °Í °°¾ÆÀÌ ´õ °ü´ëÇÕ´Ï´Ù. º¸¾Ò½À´Ï´Ù¿¡°Ô ¹°¾î "´©±¸´Â ºñƲ½ºÀÇ µå·¯¸Ó?"±×¸®°í ±×°Í ÁØ " Pete Best ÇÇÆ®°¡ ÃÖ°íÀÇ ¡°.  When I tried to put the same query on Google it gave me ¡° "ÇÕ´Ï´Ù. ¶§ µ¿ÀÏÇÑ °Ë»ö¾î¿¡·Á°í ³ë·Â ±¸±ÛÀÌ ÁØ" Ringo Starr ¸µ°í ½ºÅ¸ ' ¡°.  I am not sure if Hakia confused the ¡°Best¡± on ¡°Pete Best¡± as a ranking mechanic inside its semantic algorithm to be able to give me a best answer.  Obviously, there is still some to fix under the hood for cases like this.
