Information often implies a collection of facts and data: "A man's judgment cannot be better than the information on which he has based it" (Arthur Hays Sulzberger).
Learning usually refers to knowledge gained by schooling and study: "Learning ... must be sought for with ardor and attended to with diligence" (Abigail Adams).
Erudition implies profound, often specialized knowledge: "Some have criticized his poetry as elitist, unnecessarily impervious to readers who do not share his erudition" (Elizabeth Kastor).
Lore is usually applied to knowledge gained through tradition or anecdote about a particular subject: Many American folktales concern the lore of frontier life. Scholarship is the mastery of a particular area of learning reflected in a scholar's work: A good journal article shows ample evidence of the author's scholarship.
knowledgeartificial intelligence, information science The objects, concepts and relationships that are assumed to exist in some area of interest. A collection of knowledge, represented using some knowledge representation language is known as a knowledge base and a program for extending and/or querying a knowledge base is a knowledge-based system. Knowledge differs from data or information in that new knowledge may be created from existing knowledge using logical inference. If information is data plus meaning then knowledge is information plus processing. A common form of knowledge, e.g. in a Prolog program, is a collection of facts and rules about some subject. For example, a knowledge base about a family might contain the facts that John is David's son and Tom is John's son and the rule that the son of someone's son is their grandson. From this knowledge it could infer the new fact that Tom is David's grandson. See also Knowledge Level. (1994-10-19)
Ac*knowl"edge\, v. t. [imp. & p. p. Acknowledged; p. pr. & vb. n. Acknowledging.] [Prob. fr. pref. a- + the verb knowledge. See Knowledge, and cf. Acknow.]1. To of or admit the knowledge of; to recognize as a fact or truth; to declare one's belief in; as, to acknowledge the being of a God. I acknowledge my transgressions. --Ps. li. 3. For ends generally acknowledged to be good. --Macaulay. 2. To own or recognize in a particular character or relationship; to admit the claims or authority of; to give recognition to. In all thy ways acknowledge Him. --Prov. iii. 6. By my soul, I'll ne'er acknowledge thee. --Shak. 3. To own with gratitude or as a benefit or an obligation; as, to acknowledge a favor, the receipt of a letter. They his gifts acknowledged none. --Milton. 4. To own as genuine; to assent to, as a legal instrument, to give it validity; to avow or admit in legal form; as, to acknowledgea deed. Syn: To avow; proclaim; recognize; own; admit; allow; concede; confess. Usage: Acknowledge, Recognize. Acknowledge is opposed to keep back, or conceal, and supposes that something had been previously known to us (though perhaps not to others) which we now feel bound to lay open or make public. Thus, a man acknowledges a secret marriage; one who has done wrong acknowledges his fault; and author acknowledges his obligation to those who have aided him; we acknowledge our ignorance. Recognize supposes that we have either forgotten or not had the evidence of a thing distinctly before our minds, but that now we know it (as it were) anew, or receive and admit in on the ground of the evidence it brings. Thus, we recognize a friend after a long absence. We recognize facts, principles, truths, etc., when their evidence is brought up fresh to the mind; as, bad men usually recognize the providence of God in seasons of danger. A foreign minister, consul, or agent, of any kind, is recognized on the ground of his producing satisfactory credentials. See also Confess.
