Semantic search tools seek to improve the accuracy of web searching by considering the context (or meaning) of the terms as they occur in desirable web documents. Instead of Google's PageRank to predict relevancy, semantic search tools use the science of meaning in language to produce more relevant results for users. The goal of semantic searching is to deliver information in a meaningful context rather than having to sort through lists of documents bound by loosely-related keywords. Some authors view semantic search tools as a set of techniques to retrieve knowledge from richly-structured data sources and which enable web technologies to define domains at a sophisticated level. Semantic tools on the web are likely to rely on metadata to describe and bring together documents during information retrieval. This language will help to describe and retrieve documents much like what we encounter in medical databases. Metadata is defined as 'data about data' and the major standard in the field is Dublin Core.

Cognition Search http://www.cognition.com/
Cognition search uses a natural language mapping technology and a blend of linguistics and mathematical algorithms to locate and collate content. In effect, this helps computers to find meaning (or related concepts) with the words we use in searches. CS understands the relationship between words and phrases (meaning), paraphrases (a "finger" or a "digit") and taxonomies (a "finger" is part of a "hand", a "cow" is a "bovine" and is a "mammal"). Cognition search permits searching across four domains:
Duck Duck Go http://duckduckgo.com/
When searching Duck Duck Go, the service brings up the most 'official' page first and if the search terms are linked to a Wikipedia page, a short blurb will appear as well as related search terms at the top. DDG features special category pages, and recognizes calculations, phone numbers, zip codes, ISBNs and product codes, as well as street and IP addresses.
Evri is a technology company developing products that change the way consumers discover and engage with content on the Web. Some publishers have used Evri’s semantic platform on their sites, including the most prestigious news organizations such as the Washington Post, Hearst Publishing, Yahoo! and the Times of London. With over 2 million pages across 500 categories, several content recommendation applications and a feature-rich API platform, Evri is rapidly improving access to information.
The aim of the engine is to return meaningful sentences for the search query. Factbites offers you real, meaningful sentences that are right on topic - a technique that lies between a site summary and summary of results.
Hakia - http://hakia.com
hakia Semantic search technology is based on a computerized system that understands content and query similar to how the human brain processes natural languages. Instead of matching the occurrence of words or symbols (as done in indexing systems), semantic search systems match concepts and their meaningful variations.
Have you recently written a paper, but you're not sure to which journal you should submit it? Or maybe you want to find relevant articles to cite in your paper? Or are you an editor, and do you need to find reviewers for a particular paper?
Leksi is derived from a linguistic term "Lexical" meaning "related to words". It emphasizes language processing from the level of words and the meanings associated with them. It has been exploring more intelligent ways to find information for users in a more meaningful way. Method will bring more accurate and relevant search results than the current search tools.
NEPOMUK - The Social Semantic Desktop http://nepomuk.semanticdesktop.org/nepomuk/
Networked Environment for Personalized, Ontology-based Management of Unified Knowledge (NEPOMUK) brings together researchers, industrial software developers, and representative industrial users, to develop a comprehensive solution for extending the personal desktop into a collaboration environment which supports both the personal information management and the sharing and exchange across social and organizational relations.
NLM Plus http://nlmplus.com/
NLMplus is an innovative semantic search and discovery application, developed by WebLib LLC, a small business in Maryland, in response to a challenge contest by the National Library of Medicine (NLM) to make use of NLM’s vast collection of biomedical data and services for the benefit of the Library’s diverse worldwide user communities.
Powerset is applying its natural language processing to search, aiming to improve how we find information by unlocking the meaning in ordinary human language. Powerset is a search and discovery experience for Wikipedia and improves the entire search process. In the search box, you can express yourself in keywords, phrases, or simple questions. On the results page, questions are answered directly, and aggregated from across multiple articles.
When it comes to search, - “Meaning Matters.” It’s time for a search engine that thinks like we do, learns like we can, and interacts with us in a human-like way. PureDiscovery KnowledgeGraph is a leap forward for search that allows users to interact with a search engine conversationally as opposed to using a cryptic search language. Armed with our new approach, your organization will both maximize on-target results and minimize unproductive search time. PureDiscovery is leading a radical reinvention of search, based on a core set of beliefs.
Quertle ("Relationship-driven biomedical research -- Intelligent semantic queries") goes beyond simple term matching to identify the most salient information in the literature. Using a combination of linguistic methods, Quertle finds facts defined within documents, creating its own database of nearly 200 million relationships, and is able to report the ones that are relevant to your query. Quertle's approach is based on a thorough understanding of biology and chemistry and was built from the ground up to address the unique needs of this technical literature.
A semantic search engine out of Germany. You should look at its analysis page for a website - interesting data there. I like looking into its list of related terms, which allows you to tag surf other aspects of the inquiries meaning.
Semantic Web Search Engine http://swse.deri.org/
SenseBot (Beta) is a semantic search engine that generates a text summary of web pages on the topic of your search. It uses text mining and multidocument summarization to extract sense from Web pages and present it to the user in a coherent manner. A "Semantic Cloud" of concepts is displayed above the summary, allowing to steer the focus of the results. See some results.

TipTop Technologies, Inc. is an emerging Silicon Valley-based company founded during the summer of 2008, whose first consumer-facing product on the Internet was launched at FeelTipTop.com in June 2009. Through building some unique and powerful technology at the outset, TipTop is well-positioned to take up a leadership position in the growing market of semantic-driven products both in the consumer and the enterprise space.
The world's first AI question-answering platform. We are using our unique semantic technology to build the first internet-scale platform for directly answering the world's questions. As knowledge is added to the platform we understand and answer more and more.
This is the Watson Web interface for searching ontologies and semantic documents using keywords. The interface is subject to frequent evolutions and improvements. At the moment, enter a set of keywords (e.g. "cat dog old_lady") and a list of URIs of semantic documents will appear where keywords are as identifiers or in classes, properties, and individuals. You can use "wildcards" in the keywords (e.g., "ca? dog*"). You can restrict to particular types of entities (classes, properties or individuals) and elements within entities (local name, label, comment or any literal). For example, you can express queries like "give me the classes or the individuals using the term car in the name or in the label".
Yummly is the world’s first semantic recipe search and recommendation platform. Yummly enables you to find and customize recipes based on your personal taste, nutritional and dietary preferences. The site aggregates recipes from cooking websites, and is fully integrated with Facebook.
Use the Browser Application to browse data sources of the Semantic Web. Its UMBEL (Upper-level Mapping and Binding Exchange Layer) is a reference structure for placing content and data in context with other data. It is comprised of 20,000 subject concepts and their relationships — with one another and with external vocabularies and named entities.
