Intelligent search
Although word-based search techniques may seem to successfully find the targeted information, they usually retrieve a lot of information that isn't relevant to your query. Phrase-based search methods also "miss" important and relevant information. To improve its ability to retrieve all and only the journal information you seek, Now & Then combines a number of advanced retrieval technologies that go beyond matching words and phrases―techniques that "understand" how you, individually, use language, and recognize your world, and your worldview.

Now & Then combines:
1) its understanding of the ways you individually use language with
2) its knowledge of your unique experiences, interests, thoughts, and philosophies (your worldview)

This enables Now & Then to recognize the content and context of your searches and queries and to gather retrieve precisely the relevant information while avoiding ambiguous and unrelated information. Now & Then monitors your journal's content, your queries, your use patterns, your feedback, personalization, and your personal rules to continuously improve its search and retrieval capabilities.

Now & Then searches only journal information―it does not try to understand and search through huge stores of online information that have nothing to do with your life. As you use it, Now & Then learns about you, its user―a single, unique individual. It learns to understand the words and concepts you use to describe your activities, experiences and perceptions.

As Now & Then learns more about how you perceive the world, it makes increasingly better decisions about how your personal information should be stored, what information should be provided in response to your queries, and the information formats and presentation methods that provide crisp understanding and insight.

Now & Then's power and usefulness is continuously improved through machine learning, through your feedback, personalization, and training. Now & Then applies semantic indexing, multi-dimensional term scaling, classification, and concept clustering with Bayesian-based relevance feedback to understand your interests and worldview as they change throughout your life.

Over a lifetime, as you accumulate vast stores of journal information, the information remains you-centric. Although your interests, philosophies, personal and professional associations change dramatically, your journal information remains a special domain that can be accurately probed and explored based on Now & Then's accumulated knowledge about your evolving view of the world.
